39、mpression stroke.The fuel used has a self-ignition temperature of some 400 and therefore ignites when injected into the combustion chamber at an injection pressure of 10-25 MPa.In the petrol engine a homogeneous combustible mixture,supplied by the carburetor,is ignited by the sparking plug,but on th

40、e compression ignition engine the thorough mixing together of the fuel and air for complete combustion must be accomplished within the cylinder during some 35-40of crankshaft revolution.This presents difficulty and is accomplished by using a penetrating spray of finely-divided fuel and considerable

41、turbulence of the compressed air in the cylinder.Even so,only some 80%of air supplied can be utilized,but the spark ignition engine can consume all the air induced.Compared with the spark ignition engine the high combustion pressures need a strong,heavy and costly construction,while the fine limits

42、to which the fuel pump and injectors must be manufactured add to the expense.Even with extensive light alloy construction,the power to weight ratio is lower than for a petrol engine.Starting may present more difficulty due to the high compression pressure and the heat required for fuel ignition.Idli

43、ng is less smooth,acceleration slower,maximum rev/min are lower and imperfect combustion will result in a lower bmep and obnoxious exhaust smoke.On the other hand,the higher compression ratio gives a greater thermal efficiency and thus an increased economy km/L.The fuel is cheaper and has a much red

44、uced fire risk.Engine torque is greater at low engine speeds and in practice considerably less maintenance is required.Carbon,beyond a thin coating,does not form when the engine is operating correctly.New Words and Expressionsspark spk n.火花ratio re n.比；比率；比例inject ndekt vt.喷射，射入injector ndekt n.注射器；
