"Distribute gaswhen(phasic) " what is what point to after all? According to chief editor of Chen Jiarui of Jilin industry university " the car is tectonic " the definition that go up: "Distribute gas when (phasic) enter namely, rowSpiracleactual open hour " .

To riseEngineaerate coefficient, raise the dynamical sex of engine, into, the open of exhaust valve and shut all one is mixed ahead of schedule lag angle. When telling spiracle transmission group, " the car is tectonic " middle finger goes out: "The action of spiracle transmission group, it is to make enter, exhaust valve can be pressed distribute gas when (phasic) formulary hour leaves shut, and assure to have leave enoughly degree. " " camshaft in order to makes spiracle is mixed according to certain working sequence distribute gas when (phasic) leave in time shut, make sure spiracle has litre of enough Cheng. " " when engine works, of camshaft be out of shape meeting influence distributes gas when (phasic) . " on camshaft " the outline of cam should make sure spiracle open and the duration that shut are accorded with distribute gas when (phasic) requirement, and make spiracle has litre of appropriate Cheng to reach its to rise fall the motion curve of the process. " camshaft is pass by crankshaft when take or when chain or when of gear drive, accordingly, "When assembling crankshaft and camshaft, must will when earmark alignment, distribute gas correctly in order to assure when (phasic) with draw well hour. Distribute gas correctly in order to assure when (phasic) with draw well hour..

Through the description above we can see, distribute gas correctly when (phasic) it is the essential condition that engine works normally, once distribute gas when (phasic) wrong, the regular job that affects engine. Actually " alignment when earmark " and " distribute gas when (phasic) correct " both between namely a pair causal. "Aim when earmark " it is a reason, "Distribute gas when (phasic) correct " it is a result. Below normal circumstance, when assembling must will when earmark alignment, accordingly, when earmark alignment is to distribute gas when (phasic) mix correctly draw well is ordinal (ignition when) true premise condition, that is to say, want to distribute gas when (phasic) with draw well order (ignition when) correct, must when earmark alignment. But, notable is, when earmark alignment is not to distribute gas when (phasic) mix correctly draw well is ordinal (ignition when) true sufficient condition, that is to say, although when earmark was aimed, distribute gas when (phasic) with draw well order (ignition when) not certain also correct. Because,this is, when have in transmission system a lot ofSpare parts, crankshaft adopts key drive or be filled with too cooperate means to drive crankshaft when tine (catenary) annulus, repass when take or when chain belt moves camshaft when tine (catenary) annulus, camshaft when tine (catenary) annulus in adopt key drive or be filled with too cooperate means to drive camshaft, camshaft repass holds out drive of column, tappet, rocker or direct drive valve to leave shut, a lot of link exist among this, among them any link appears problem, for example, key amlposition, when belt ageing, when chain wears away, camshaft is out of shape or wear away, spiracle clearance mistake or hydraulic pressure hold out column
