The decline of the electric vehicle was brought about by several major developments, such as a better system of roads in America By the 1920s, lower gasoline car price than electric cars due to the initiation of mass production of internal combustion engine vehicles by Henry Ford, the discovery of Texas crude oil and the invention of the electric starter in 1912 eliminating the need for the hand crank*1.
1.1 The Development of Electric Vehicles
The early electric vehicles, such as the 1902 Wood's Phaeton (Figure 1.1), were little more than electrified horseless carriages. The Phaeton had a range of 18 miles, a top speed of 14 mph and cost $2,000.

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.

3.5 Automtomatic transmission with hydrodynamic converter (AT)-Conventional automatic transmission Torque converter ( Fig.3-10 ) serves as a starting clutch to facilitates smooth and comfortable drawing away, transmits and multiplies the engine torque, and damps engine torsional vibrations. gear systems are used to multiply torques, reduce speeds and reverses the direction of rotation for the reverse gear. Most automatics use the planetary gear sets (Fig.3-11). The commonly used planetary gears are Ravigneaux set and Simpson set. A simple planetary-gear set can also be connected to the upstream or downstream of a Ravigneaux set or Simpson set. Either the outer gear or the sun gear may be held stationary, providing more than one possible torque multiplication factor for each set of gears. Also, if all three gears are forced to rotate at the same speed, the gear set forms, in effect, a solid shaft.

Engine load is transmitted to the computer by means of an intake manifold absolute pressure sensor. The sensor converts manifold vacuum into a small electrical signal. This input allows the computer to increase fuel supply when the engine is under load and needs a richer mixture, and decrease fuel supply when engine load is light. Every injection system has a temperature sensor to measure engine coolant temperature. Many injection systems have an additional sensor to measure the temperature of the incoming air. Some late model fuel injection systems monitor the amount of air entering the engine by using an airflow sensor（Fig.2-10）. The computer takes this input and compares it with engine RPM and manifold vacuum to determine the amount of fuel to inject. There are three types of airflow sensors, the heated wire, the air valve and the Karmann vortex.

7. Valve Drive Mechanism It is used to transfer the camshaft lift The valve drive mechanism consists of the lifters, the pushrods and the rocker arms Lifters change the rotary motion of the camshaft to reciprocating motion to open and close the valve. Hydraulic lifters are used to reduce noise and control the valve clearance on many engines. They absorb the valve train clearance by using oil pressure inside the lifter body. Pushrods are used only on engines that have the camshaft placed within the block. Overhead camshafts do not need pushrods. Rocker arms are designed to change the direction of the cam lifting force.

Chapter 6 Automotive Electrical and Electronic Systems
ration of an adaptive cruise control system (ACCS) is the same as a conventional system except when a signal from the headway sensor detects an obstruction, in which case the vehicle speed is decreased. If the optimum stopping distance cannot be achieved by just backing off the throttle, a warning is supplied to the driver. A more complex system can also take control of the vehicle transmission and brakes but this, while very promising, is further behind in development. It is important to note that adaptive cruise control is designed to relieve the burden on the driver, not take full control of the vehicle!

6.4 Ignition Systems
On some vehicles, there is an individual coil for each cylinder mounted directly on top of the spark plug. The independent ignition system with integrated ignition modules into each coil assembly typically use four wires connected to the primary side of the assembly (Figure 6-12). The four wires consist of battery positive, ground, ignition timing signal, and ignition confirmation signal. The PCM uses the ignition confirmation signal to determine if a coil is not operating. The primary circuits of these coils cannot be tested with an ohmmeter. This design completely eliminates the high tension spark plug wires for even better reliability. Most of these systems use spark plugs that are designed to last over 100,000 miles, which cuts down on maintenance costs.

A circuit may be protected by a special wire that acts as a fuse. This wire is called a fusible link.
A Circuit breaker feeds current through a bimetallic strip and a set of points to the remainder of the circuit. When the current exceeds the breaker’s rating, the bimetallic strip heats and bends to separate the points. Once it cools, it will close the circuit.

Modern internal combustion engines are started by using electric starting motor, or starter (Figure 6-6, 6-7 and 6-8). A starting system consists of battery, ignition switch, starter relay and starter. To energize the starter, the ignition switch is turned to START, which completes an electrical circuit. When the starter begins to turn the starter gear moves out and engages the ring gear, which spins the crankshaft.

6.1 Lead Acid Battery and Circuit protection
devices
6.1.1 lead-acid storage battery A lead-acid storage battery (Figure 6-1) is an electrochemical device that produces voltage and delivers electrical current. The battery is the primary "source" of electrical energy used in vehicles today. When charging, the battery converts electricity into chemical energy, and when discharging, it converts chemical energy into electricity, producing a current. 6.1.2 Circuit protection devices It is necessary to protect electrical circuit against shorting (accidentally touching ground) that could burn up the wiring. Electrical units must be protected against overloads also. In circuits, Circuit protection devices must be installed in series with the electrical devices or wiring to be protected. The common types of circuit protection devices are fuse, fusible link and circuit breaker, see Table 6-1.

Chapter 6 Automotive Electrical and Electronic Systems
A circuit may be protected by a special wire that acts as a fuse. This wire is called a fusible link.
A Circuit breaker feeds current through a bimetallic strip and a set of points to the remainder of the circuit. When the current exceeds the breaker’s rating, the bimetallic strip heats and bends to separate the points. Once it cools, it will close the circuit.

Modern internal combustion engines are started by using electric starting motor, or starter (Figure 6-6, 6-7 and 6-8). A starting system consists of battery, ignition switch, starter relay and starter. To energize the starter, the ignition switch is turned to START, which completes an electrical circuit. When the starter begins to turn the starter gear moves out and engages the ring gear, which spins the crankshaft.

devices
6.1.1 lead-acid storage battery A lead-acid storage battery (Figure 6-1) is an electrochemical device that produces voltage and delivers electrical current. The battery is the primary "source" of electrical energy used in vehicles today. When charging, the battery converts electricity into chemical energy, and when discharging, it converts chemical energy into electricity, producing a current. 6.1.2 Circuit protection devices It is necessary to protect electrical circuit against shorting (accidentally touching ground) that could burn up the wiring. Electrical units must be protected against overloads also. In circuits, Circuit protection devices must be installed in series with the electrical devices or wiring to be protected. The common types of circuit protection devices are fuse, fusible link and circuit breaker, see Table 6-1.
