8 486 PL ENGINE P UNIQUE FEATURES OF 486 PL ENGINE l Electronically controlled sequential fuel injection engine : Fuel Injection and Ignition are controlled through Intelligent microprocessor programmed to give best performance under all operating conditions. 486 PL EMS-ECU is located on LH side firewall below glow box assembly. Fig 1 l Distributor-less ignition system : Ignition timing controlled through mapped data of ECU and hence no tuning / adjustment / required. Maintenance free. l Better starting under all operating conditions : No need to give choke for cold start. No hot start problem. l Four valves per cylinder : Technology for improved engine breathing and performance. l Hydraulic tappets : Zero tappet clearance at all times and no tappet adjustment and maintenance required (Self adjusting tappets). Maintenance free. l Canister purging : Through ECU for good startability and smooth running under all operating conditions. l Fuel cut off during coast down / deceleration to save fuel. l Intank fuel pump : Self priming fuel system. No fuel vapour lock under hot soak / summer conditions. l Knock sensor : Knock sensor fitted on the block to sense the engine knock and give the feed back to ECU to adjust the igni t ion for smooth engine operation (and to prevent engine damage in case of poor quality of fuel used). l Fuel circuit inertia switch : In case of Impact / accident the inertia switch automatically cuts off fuel supply thus prevent any fire hazard due to fuel spillage (The switch can be reset by thumb press). The iner tia switch is located at LH 'A' pillar lower trim below dashboard. Fig 2 INERTIA SWITCH 486 PL EMS-ECU Fig. 1 Fig. 2
