Description
Technical field
The present invention relates to a kind of cylinder configuration framework of multistage type variable air displacement engine, be particularly related to a kind of cylinder displacement configuration by non-equivalent, enabling the more air displacement combination of multistage can adjust with the running condition of vehicle, the maximization engine further improves vehicle oil consumption in the running ratio in more fuel-efficient zone.
Background technique
The fuel-efficient optimum operation point of general gas car internal combustion engine is distributed in the high load area of engine speed 2000～3500rpm mostly, yet general gas car because of only needing partly load, seldom runs on this more fuel-efficient zone in the kenel of travelling in urban district; Based on the economic needs that reduces oil consumption, at present known is in engine utilization valve system start control technique, look traveling state of vehicle elasticity and adjust the air displacement of engine, make engine when hanging down load condition, cylinder number running that can be less, except that the moving loss of the pump that reduces engine air admittance (Pumping Loss), and can increase the running ratio of engine, improve vehicle oil consumption by this in more fuel-efficient zone; Its principle is to control by the valve system start, make engine when some specific low load condition, can make advancing of partial cylinders, the exhaust valve closure, enter fuel-efficient operation mode, and when heavy duty, control the valve standard-sized sheet again and revert to big air displacement, for keeping the engine balance, all design at present and when underload, turn off half cylinder, for example on the eight cylinder engines of Chrysler and general (GM) gas car only with four cylinders, then only use three cylinders on the six cylinder engines of Honda gas car, right this existing in prior technology disappearance is, because of the air displacement of each cylinder all identical, so only making the air displacement operation mode of two-part, engine switches, for example, in-line multi-cylinder engine 10 with multi cylinder 11a～d shown in Figure 1, all cylinder 11a～d of may command open and do big air displacement running, or control two cylinder 11a wherein, 11b closes, only with all the other two cylinder 11c, 11d does the running of float tolerance, or have the V-type of multi cylinder 21a～f or level as shown in Figure 2 to the multi-cylinder engine 20 that crouches, all cylinder 21a～f of may command open and do the running of big air displacement, or control wherein three cylinder 21a～c close, only do the running of float tolerance with its excess-three group cylinder 21d～f; So because of road conditions or other factors influence, the actual engine rotation speed change is indefinite, is not that two kinds of loads of height are only arranged, therefore, if can enlarge the practical range of variable air displacement running, then can strengthen the running ratio of engine again, further improve vehicle oil consumption in more fuel-efficient zone.
Summary of the invention
The object of the present invention is to provide a kind of cylinder configuration framework of multistage type variable air displacement engine, cylinder displacement configuration by non-equivalent, enabling the more air displacement combination of multistage can adjust with the running condition of vehicle, the maximization engine further improves vehicle oil consumption in the running ratio in more fuel-efficient zone.
