Abstract

The invention relates to an ignition type engine throttle-valve-free air intake system. The system comprises an air intake pipe (2), a pressurizer (4), an intercooler (7), an intercooler air outlet pipe (5) and an engine (1) which communicate in sequence. The pressurizer (4), the intercooler (7) and the engine (1) are connected with an electronic control unit (9), the air intake pipe (2) and the intercooler air outlet pipe (5) communicate through a butterfly valve (6), and the electronic control unit (9) carries out opening degree control over the butterfly valve (6). Compared with the prior art, a throttle valve is not needed, engine pump gas losses are reduced, and the economic property of the engine is improved.

Description

technical field [0001] The invention relates to the field of engine electronic control, in particular to an ignition-type engine throttleless air intake system and a power control method. Background technique [0002] The ignition engine system gas enters the cylinder and passes through the air filter, supercharger, intercooler, throttle valve and intake manifold in turn. The throttle valve can adjust the intake air volume, but the throttle valve brings the engine pumping loss, which reduces the engine pressure. economic performance. [0003] There are many ways to realize the engine air intake system without throttle valve. At present, the adjustment of intake air volume is mainly realized through the adjustment of valve timing, valve opening duration and valve lift. It puts forward higher requirements for the engine gas distribution system, which brings about a substantial increase in cost. At the same time, for some heavy-duty ignition engines, such as commercial vehicl...
