Abstract
The invention provides a control method of air intake and air exhaust valves of an internal combustion engine, which belongs to the field of air intake and air exhaust systems of internal combustion engines. The control method of the air intake and air exhaust valves is based on thermodynamic cycle of high pneumatic compression ratio and low expansion ratio so as to ensure that the air exhaust valve is opened as soon as possible and the opening/closing time of the air intake valve is properly adjusted when a turbocharged internal combustion engine is under a low-speed and large-torque working condition, a highland operation working condition and an acceleration working condition, therefore, air intake flow is ensured to be increased as much as possible under the working conditions. Meanwhile, a passage is arranged between an air intake pipe behind a compressor and an air exhaust pipe before a turbocharger; air of low temperature is introduced into the air exhaust pipe to reduce exhaust temperature so as to protect the turbocharger; when cold start is carried out, the air exhaust valve is opened later to enhance compression temperature in a cylinder; and once the start is carried out, the air exhaust valve is opened early to increase the air intake quantity. The control method can largely enhance the dynamic property of the internal combustion engine under the low-speed and large-torque working condition and the highland working condition, improve the start performance and acceleration performance of the internal combustion engine and enable the internal combustion engine to obtain a better emission performance.
Description
Technical field
The present invention relates to a kind of internal combustion engine air-exhausting air-entering door control method, belong to the internal combustion (IC) engine air-inlet-exhaust system field.
Background technique
Along with sharply increasing of automobile pollution, the rising steadily of world petroleum price, how atmospheric pollution phenomenon serious day by day improves the energy utilization rate of internal-combustion engine and reduces the problem of discharging urgent day by day effectively.Mainly there is following problem at present:
1) because this new technology of turbosupercharging can improve the rate of combustion of internal-combustion engine well, reduce the discharge of harmful gases amount, internal-combustion engine is equipped with the main trend that turbosupercharger becomes internal combustion engine development, but, the heat load of swirl vane and mechanical load is too high, reduce the problems such as the obvious variation of responsiveness that boost pressure rises under the serious and instantaneous conditions of fuel consume under serious, the low-load in engine torque under the low speed under big load at a high speed.
2) then mechanical loss is low owing to the internal-combustion engine low cruise, the big more then driving force of the low-speed big that internal-combustion engine has is strong, therefore, internal-combustion engine has the trend to the low-speed big development, and how to make internal-combustion engine good operation under low-speed big of being furnished with turbosupercharger become a big problem of being badly in need of solution.
3) simultaneously because after suction pressure increased, valve keying rule increased greatly to the influence degree of internal-combustion engine breathing action, therefore, the exploitation of changeable air valve technique system and how most important to its research of carrying out controlling method.
Summary of the invention
The objective of the invention is to problem, proposed to reach the scheme that the internal-combustion engine have turbosupercharger can good operation in full operating mode scope that solves by choosing suitable variable valve system and inlet and exhaust valve controlling method reasonable in design at above-mentioned internal-combustion engine research field.
The technical solution adopted for the present invention to solve the technical problems is: a kind of internal combustion engine air-exhausting air-entering door control method, be positioned at the variable inlet and exhaust valve system of turbocharging internal-combustion engines cylinder head by ECU (Electrical Control Unit) control, described variable air inlet door system comprises oil feeder, electric liquid valve actuating mechanism, connects oil circuit and solenoid valve; Described variable exhaust door system comprises the exhaust valve cam phase regulator; For the variable air inlet door system, the 1st control signal is controlled the 1st solenoid valve in the unlatching timing in fuel feeding stage, the unlatching timing of decision intake valve; The 2nd control signal is controlled the unlatching duration of the 1st solenoid valve, the lift of decision intake valve; The 3rd control signal is controlled the 1st solenoid valve in the unlatching timing in draining stage, the decision intake valve close timing; For the variable exhaust door system, the 4th control signal control exhaust cam is with respect to the phase place of bent axle, the unlatching timing of decision exhaust valve; For suction tude behind compressor and the air valve between the outlet pipe before the turbosupercharger, control by the 5th control signal.In order to realize the good operation of turbocharging internal-combustion engines in full operating mode scope, the present invention matches turbosupercharger as design conditions and optimizes changeable air valve control parameter according to the rotating speed of Max. torque correspondence, and the changeable air valve control parameter that defines this operating mode is as the benchmark Control Parameter of controlling variable valve system under other operating modes, on this basis, the present invention adopts different controlling methods according to the difference of internal combustion engine operation operating mode to variable valve system:
