Results of compression test:

2008-01-21T01:03:00.001-08:00

Compression guage reading	Probable engine condition
Fails to climb during all compression strokes	Valve sticking open
20 PSI below normal	Faulty rings or valve seating
More than 20 PSI below normal	Faulty head gasket
20 PSI above normal	Excessive carbon built up in combustion chamber

1) Testing the battery:

Some maintenance free batteries do not have a charge indicator at the top. To find the state of charge measure the open circuit voltage. Measuring terminal voltage with a digital voltmeter usually makes this test. A battery with a OCV of 12.40 volts is charged enough for testing, if the voltage is less than 12.40 volts then battery needs to be charged.

Engine testing instruments:

2008-01-21T01:02:00.001-08:00

To diagnose or to measure the performance and service of engine, requires the use of various test instruments and guages.

1) Tachometer:

The tachometer measures engine rpm; the tach may be electric, optical, or magnetic. It counts the electric pulses in the ignition system and reports the result as engine speed. This tells the driver how fast the engine crankshaft is turning. Electrical or optical tachometers are used in the shop. The electric tachometer connects to the ignition primary circuit. The teach counts the number of times per second the primary circuit opens and closes. The optical tachometer has a light beam focused on a rotating part such as engine crankshaft pulley. The teach counts how many times per second a mark on the pulley passes by.

2) Dwellmeter:

The dwellmeter elctrically measures how long the contact points remain closed during each ignition cycle of a contact point ignition system. The average of all cylinders is then displayed in degrees of distributor-cam rotation. The technician can also use the dwellmeter to set contact point gap and to check for unwanted dwell variation as engine speed increases. Excessive variation indicates mechanical trouble in the distributer. In the electronic control system, the ECM controls dwell and it is not adjustable. The dwellmeter is used to check the duty cycle of the mixture control solenoid in a feedback carburetor. A dwell tach meter is a single meter is a single meter that serves as both a dwellmeter and tachometer. This is possible because both meters have two leads and require same connections. Pushing a button or turning a knob on the meter switches the reading from rpm to dwell.

3) Cylinder compression tester:

The cylinder compression tester measures the ability of the cylinders to hold the compression while the starting motor cranks the engine. The compression tester is a pressure guage that measures the amount of pressure or compression, built up in the cylinder during the compression stroke. How well a cylinder holds compression is an indication of the condition of the piston, piston rings, cylinder wall, and valves and head gasket.

The spark plugs must be removed to use the compression tester. Before removing the spark plugs, be sure that engine is at normal operating temperature and the battery is fully charged. Use compressed air to blow out dirt or dust through spark-plug wells. Another way is to disconnect the cables, loosen spark plugs to one turn and reconnect the cables. Then start engine, run the engine for few seconds at 1000rpm. The leaking combustion gases will blow the dirt out of plug wells.

Remove the spark plugs block the throttle wide open so that the maximum amount of air enters the cylinders. Thread the compression tester adapter into spark plug hole of number 1 cylinder. Disable ignition to prevent coil damage from high voltage arcing. Disable the electric fuel pump; operate the starting motor to crank the engine through four compression strokes. The needle on the compression guage will move to show the maximum compression pressure in the cylinder.

Body design:

2008-01-09T23:24:00.000-08:00

Body design:

There are many body styles although they may look different all body shapes should slip through air with minimum resistance. There are three main types of body construction.

Body and frame
Unitised body
Space frame

Today a few cars have separate body and frame. Trucks usually have this type of construction. The chasis usually includes everything except body.

The unitized body does not have a separate frame. The body panels are welded together. A short stub frame or engine cradle fastens under the bottom front of the body. This provides needed strength and mounting points for the engine, suspension and steering parts. The cradle and sub frame must be properly positioned to avoid a wheel alignment problem.

Space frame type of body construction is made of steel stampings welded together. This is similar to the tube chassis and roll cage in a race car. Plastic panels fasten to the space frame to complete the body. Most bodies are sheet steel shaped and then welded together. Some body parts and panels such as hood are aluminum a light metal. Other panels and even complete bodies are fiberglass or plastic.

The electrical & electronic control systems:

2008-01-09T23:23:00.002-08:00

The electrical system:

Electricity powers most of the devices in the car. The starting motor requires electricity to crank the engine, the ignition system requires electricity to deliver spark inside the cylinders. The fuel injectioin system, lights, horns, radio, air conditioner and other accessories require electricity to operate. The battery supplies electricity while the engine is off and for cranking the engine. After the engine starts, the alternator recharges the battery and supplies power for the electrical load.

The electronic control systems:

Many devices and systems on the car require a control system for safe and proper operation. A basic control system has three parts. These are inputs, the control unit and the outputs. The inputs are switches and sensors; they provide information to electronic control modules (ECM). Then the ECM signals the output devices or actuators to take the required action. The ECM has a self-diagnostic capability. This means a memory stores information about faults or malfunctions that have occurred and perhaps disappeared. When recalled from the memory this stored information helps the technician to diagnose and repair the vehicle.

The braking system:

2008-01-09T23:23:00.001-08:00

To apply the brakes the driver pushes down on the brake pedal. This sends fluid under pressure to a brake assembly to each wheel. In the brake assembly the fluid forces a stationary part against a rotating part. The friction between the two parts slows or stops the rotating part and wheel. This slows and stops the car.

Many vehicles have an electronic brake system. It prevents wheel from locking during braking. A locked wheel is not very effective in stopping the vehicle. The tyre skids and looses braking ability. The anti lock braking system automatically reduces the pressure on the fluid at each wheel that is about to lock. This provides the most efficient braking.

The steering system:

2008-01-09T23:22:00.002-08:00

The steering system enables the driver to turn the front wheels left or right. Steering starts at the steering wheels in front of the driver. As it is turned, shafts and gears act on the linkage, which connects, to the front wheels. The wheels swing to right or left. A few vehicles have four wheel steering. When the front wheels swing to one side the rear wheels also swing slightly, which improves high-speed stability. The steering system can be power assisted, hydraulic or mechanical linkage type.

The suspension system:

2008-01-09T23:22:00.001-08:00

Springs, shock absorbers and related parts between the wheels and the car body make up the suspension system. A spring at each wheel supports the weight of the vehicle and the load it is carrying. The springs allow the wheels to move up and down as they meet bumps on the road. Automobile suspension systems use four types of springs. These are coil springs,leaf springs, torsion bar springs and air springs. Some cars have electronic ride control which automatically changes the firmness of the shock absorbers to suit road conditions.

Engine

2008-01-09T23:21:00.001-08:00

Identifying the drive wheels:

The way the engine mounts itself usually tells us which wheels are drive wheels. These wheels drive the car. If the engine mounts longitudinally, the car usually has rear wheel drive. Engine power flows through the transmission and drive shaft to the rear wheels. However, some rear wheel drive vehicles may also drive front wheels. These vehicles usually have a transfer box. It can send or transfer some of the engine power to the from wheels. This is called four wheel drive or all wheel drive.

If the engine mounts traversly at the front of the vehicle , the vehicle has front wheel drive. Engine power flows through the trans axle to the front wheels.

The engine:

The automotive engine is an internal combustion engine. Burning a mixture of air and fuel inside cylinders in engine produces power. Each cylinder is a tin can in which a round piston slides up and down, this movement is carried through gears and shafts to rotate the wheels and move the car. To continue running an engine must have four supporting systems. These are the fuel, ignition, cooling and lubricating systems.

Some fuel systems use carburettor that mixes air and fuel into a combustible mixture. Instead of a carburettor most engines have electronic fuel injection. An electronic control module or computer controls fuel injectors; whenever engine needs fuel a signal from ECM opens the injector, fuel then sprays into the engine cylinders.

The ignition system provides sparks for the power stroke. Today all ignition systems are electronically operated. Many use an ignition distributer to distribute the sparks to proper engine cylinders.

The lubricating system keeps all moving parts inside the engine coated with layers of oil. It reduces wear and allows the parts to move freely. The oil pan at the bottom of the engine holds oil. The engine drives an oil pump that picks up oil from the oil pan and sends the oil throughout the engine for circulation.

The cooling system removes just enough heat so the engine runs at proper temperature. A water pump circulates liquid called coolant between the engine and radiator. Outside cooler air flows through the radiator that picks up and carries away the excess heat. A thermostat helps to keep the coolant at proper temperature. A fan helps to keep air moving through the radiator.

The power train:

The drive train or power train carries power from engine to drive wheels. Major power train parts may include clutch, transmission or transaxle, transfer case, driveshaft and differential. Transmissions and transaxles may be either automatic or manual. The transmission or transaxle provides several forward gear ratios between the engines and drive wheels. Gear ratio is the difference in rotating speed between the engine and the wheels. Reverse allows the vehicle to move backward. Neutral disengages all gears for starting and running the engine without moving the vehicle.

When the engine is running slowly it cannot produce enough power to get the vehicle moving. The transmission gear ratios provide the necessary increase in torque.

In automatic transaxles or transmission, it shifts automatically to match the driving conditions. For example, when the car is going up a steep hill the transaxle will downshift. This allows the engine to turn faster and produce more power. Automatic transmissions and transaxles are controlled primarily by devices that react to vehicle speed and engine load. An eletronic unit controls when and how transmission shifts.

Construction of automobile

It consists of following systems:

An engine or power plant that produces power to move vehicles.

A power train to carry the power from engine to drive wheels.

A suspension system that absorbs the shock of the tyres meeting bumps or pot holes of the road.

A steering system to give direction to the vehicle.

A braking system to stop or slow down the vehicle.

An electrical system to provide electricity for cranking the engine, charging the battery and powering the lights and other electrical equipments.

A body that provides enclosures or compartments for engine, passengers and luggage.

Maruti Udyog Limited (MUL)

2008-01-09T23:19:00.000-08:00

Maruti Udyog Limited (MUL) was established in Feb 1981 through an Act of Parliament, to meet thegrowing demand of a personal mode of transport caused by the lack of an efficient public transport system.

Suzuki Motor Company was chosen from seven prospective partners worldwide. This was due not only to their undisputed leadership in small cars but also to their commitment to actively bring to MUL contemporary technology and Japanese management practices (which had catapulted Japan over USA to the status of the top auto manufacturing country in the world).

A licence and a Joint Venture agreement was signed between Govt of India and Suzuki Motor Company (now Suzuki Motor Corporation of Japan) in Oct 1982. The first vehicle produced by maruti was in dec 1983.

The automobile has become a trusted and valuable servant of many people. Engineering design and manufacturing skill have made the modern car simple to operate and economical to maintain. To achieve utmost simplicity of operation and to assure greatest utility, engineers have made many design improvements and have added many new devices from time to time. Self-starter, synchromesh transmission, antilocking braking sensors, MPFI technique, air bag systems, power steering etc. are some of the examples.

The increasing complexity of the machine plus the improving skill with which it is manufactured, has extended a challenge and provided a opportunity for automobile mechanics who, in garages and service stations all over the country do their part to keep cars rolling.

About 15000 separate parts put together to make an automobile. These parts are grouped into several systems. Each system is made up of two or more parts that work together to perform a specific job. The basic parts or systems in automobile are Engine, Power train, Suspension system, Steering system, Braking system, Electrical system, Safety system and body.

Maruti has launched 14 successful models in collaboration with Suzuki in India and has presented a wide range of models starting from Maruti 800 to Grand Vitara.It comes with Hi tech engine with 32-bit ECM providing better fuel efficiency and performance. Maruti is also the first company to launch bi-fuel car which can operate on gasoline and LPG as well in

India

The details of all the models are disscussed in the later part of report.
