  • Page 60 3-1. GENERAL DESCRIPTION 1) Engine The engine is water-cooled, in line 4 cylinders, 4 stroke cycle gasoline unit with its S.O.H.C (Single overhead camshaft) valve mechanism arranged for “V’‘-type valve configuration. This single overhead camshaft is mounted over the cylinder head; it is driven from crankshaft through timing belt, and no push rods are provided in the valve train system.
  • Page 61 2) Engine Lubrication The oil pump is of a trochoid type, and mounted on the crankshaft at the crankshaft pulley side. Oil is drawn up through the oil pump strainer and passed through the pump to the oil filter. The filtered oil flows into two paths in cylinder block. In one path, oil reaches the crankshaft journal bearings.
  • Page 62 3) Cylinder Head and Valve Train The cylinder head is made of cast aluminum alloy and has four combustion chambers arranged in-line. Each combustion chamber has an intake and an exhaust ports. Moreover, as shown in Figure 3-l-3, the air induction nozzle is provided near each intake valve. During intake stroke of the engine, air/fuel mixture enters into the combustion chamber from carburetor through intake manifold and intake valve.

  • Page 157 POSITIVE CRANKCASE VENTILATION (PCV) SYSTEM (Blow-by gas recycling system) The blow-by gas in the crankcase flows through the passage in the cylinder block into the cylinder head. The oil particles are separated from the blow-by gas by the oil separating unit in the cylinder head cover. The gas is then returned together with the fresh air coming from the air cleaner through the PCV valve into the intake manifold for recombustion.
  • Page 158 THERMOSTATICALLY CONTROLLED AIR CLEANER (TCAC) SYSTEM This system helps to improve fuel vaporization by controlling the temperature of the intake air almost at a constant level automatically regardless of driving conditions and outside temperature, to distribute the mixture to each cylinder evenly and to stabilize the air/fuel mixture ratio. It consists of the therm0 sensor (therm0 valve) and the Air Control Actuator (ACA).
  • Page 159 EVAPORATIVE EMISSION CONTROL SYSTEM An evaporative emission control system is used to prevent emission of fuel vapors from the vehicle fuel system. The system allows evaporating fuel vapors to be stored, when the engine is not running. This is accomplished by venting the fuel tank and carburetor float chamber through a vapor storage canister containing activated charcoal.
  • Page 160 HOT IDLE COMPENSATOR (HIC) HIC attached to the air intake case serves to provide the optimum air/fuel mixture during hot idle so as to ensure stable idle speed. by this, the valve in HIC starts to open and it reaches to the full open state at about 70°C (158” F). While the engine at idle, the throttle valve is closed and the vacuum in the intake manifold stays high.
  • Page 161 DECELERATION MIXTURE CONTROL SYSTEM This system consists of a MCV (Mixture Control Valve), jet and vacuum hoses. This system is designed to introduce fresh air into the intake manifold to reduce generation of excessive HC and CO emission caused by temporary rich air-fuel ratio while rapid deceleration. The MCV has a pressure balancing orifice and check valve on its diaphragm, and closes when manifold vacuum is constant.
