1.1 Basic Parts of Automobile
1.1.1 Engine
The engine acts as the power unit. There are two types of engine: gasoline engine (also called a spark-ignition engine) and diesel engine (also called a compression-ignition engine). All engines have fuel, exhaust, cooling, and lubrication systems. Gasoline engines also have an ignition system. The ignition system supplies the electric spark needed to ignite the air-fuel mixture in the cylinders. The fuel system stores liquid fuel and delivers it to the engine. The fuel is mixed with air to form a combustible mixture in the carburetor, the manifold, or the cylinders themselves. The cooling system removes excessive heat from the engine. Air and a coolant are used to carry away the heat. The lubrication system is important in keeping the engine running smoothly. Motor oil is the lubricant used in the system.

Ultra-lean Combustion Mode. Under most normal driving
Chapter 2 Internal Combustion Engine 2.7 Gasoline direct injection
Two main operating modes of Volkswagen AG's fuel stratified injection (FSI) which uses more operating modes and FSI’s fuel-saving potential is shown in Figure 2-16. A typical pulse injection system with direct injection is given in Fig.2-17.
Chapter 2 Internal Combustion Engine 2.7 Gasoline direct injection
conditions, up to speeds of 120 km/h, the Mitsubishi GDI engine operates in ultra-lean combustion mode, resulting in less fuel consumption. In this mode, fuel injection occurs at the latter stage of the compression stroke and ignition occurs at an ultra-lean air-fuel ratio of 30-40. This operating mode is also called as stratified-charge mode. Superior Output Mode. When the GDI engine is operating with higher loads or at higher speeds, fuel injection takes place during the intake stroke. This optimizes combustion by ensuring a homogeneous, cooler air-fuel mixture which minimizes the possibility of engine knocking. This mode is also called as homogeneous-charge mode.

An automobile body (Fig.1-2) provides a protective covering for the engine, passengers, and cargo. The body is designed to keep passengers safe and comfortable. The body styling provides an attractive, colorful, modem appearance for the vehicle. It is streamlined to lessen wind resistance and to keep the car from swaying at the driving speeds.
