THE MAJOR SUPPORT SYSTEMS OF AN ENGINE ARE : FUEL SYSTEM INTAKE SYSTEM EXHAUST SYSTEM COOLING SYSTEM SYSTEMS IN AN AUTOMOBILE A. POWER TRAIN SYSTEM • POWER PLANT (POWER GENERATION - ENGINE) • ENGINE • FUEL SYSTEM • INTAKE SYSTEM • EXHAUST SYSTEM • COOLING SYSTEM • DRIVE LINE (POWER TRANSMISSION ) • CLUTCH • GEAR BOX/TRANSMISSION • TRANSFER CASE • DIFFERENTIAL • WHEELS/TYRES B. RUNNING SYSTEM • SUSPENSION • STEERING • BRAKING C. COMFORT SYSTEM • HVAC/AC/HEATER SYSTEM • SEATING/UPHOLSTRY/FACIA/INSTRUMENTS • AUDIO/VIDEO/GPS ENGINE SUPPORT SYSTEMS FUEL SYSTEM • FUEL SYSTEM IS THE HEART OF THE ENGINE • IT TRANSPORTS FUEL FROM THE FUEL TANK AND INJECTS IT UNDER HIGH PRESSURE IN TO THE ENGINE • FUEL INJECTION SYSTEM IS A HIGH PRECISION, HIGH TECHNOLOGY PRODUCT • FUEL INJECTION PUMPS ARE OF 2 TYPES - INLINE PUMP & ROTARY PUMP • IN INDIA, MICO & DELPHI-TVS MANUFACTURES FUEL INJECTION SYSTEM • COMPONENTS OF FUEL SYSTEM ARE : • FUEL INJECTION PUMP(FIP) • FUEL TRANSFER PUMP • FUEL INJECTORS • FUEL FILTERS • FUEL LINES FUEL SYSTEM INLINE PUMP INJECTOR MICO ENGINE OVERFLOW FUEL TANK FIP SUPPLY TRANSFER PUMP PRIMER ROTARY PUMP MICO/DELPHI-TVS FUEL FILTER ENGINE FIP FUEL TANK FUEL SYSTEM COMPONENTS 1. FUEL INJECTION PUMP - Fuel injection pump sucks fuel from the tank , pressurises the fuel to approx. 600 - 1000 bar and sends it to the injectors. • Inline FIP - Has separate pumping chambers for each cylinder • Rotary FIP(Distributor pump) - Has one pumping chamber and the pump distributes to each cylinder as per sequence- firing order 2. INJECTORS - Inject the high pressure fuel in to each cylinder. 3. FUEL FILTER - Filters the fuel from dirt & sediments, since the Fuel injection pump requires clean fuel. SYSTEMS IN AN AUTOMOBILE A.
