Abstract
The invention discloses an engine control device without a throttle valve, and relates to an engine control device, in particular to an engine device which is not provided with the throttle valve and can accurately control the air inflow of an engine. The device consists of a camshaft, a valve seat and a movable mechanism, wherein the camshaft is connected with a cylinder cover or a cylinder body through a bearing and a support; the movable mechanism is connected on the camshaft; one end of the camshaft is connected with a camshaft gear or a pulley central spline groove through a spline; one side face of a cam on the camshaft is an inclined plane; and the bottom of the valve seat is contacted with the inclined plane of the cam of the camshaft. In the device, the throttle valve is eliminated, so that air flow can freely and smoothly flow in an air inlet pipe, the air inflation efficiency of each cylinder is improved, the consumption of fuels is reduced, and the emission is reduced; and the reaction capacity and the smooth power output of the engine are improved.
Description
Technical field
The present invention relates to a kind of engine controlling unit, particularly a kind of non-air throttle also can accurately be controlled the engine device of air input of engine by air size.
Background technique
Former engine cam only is to control engine air valve lift, can not regulate engine speed, watt level, engine speed and watt level will be regulated by the closure that is installed on the engine air inlet tube, realize engine speed height, output power size.Closure is being opened, is being closed in the closed procedure and can cause motor suction pump and restriction loss easily to produce flow-disturbing, influence smooth and easy flow of air-flow in suction tude, cause the motor inflation bad, influencing multicylinder engine especially makes the air inflow of every cylinder inhomogeneous, charging efficiency is low, incomplete combustion, thus engine power performance influenced, defective such as fuel economy and exhaust emission are big.
Summary of the invention
Purpose of the present invention is intended to overcome the defective of prior art, a kind of no motor closure is provided, utilize camshaft just can realize the accurate control of air input of engine by air size, and can allow air-flow in suction tude, flow freely and smoothly, improve cylinder charge efficient, the engine controlling unit of the non-air throttle of energy-saving and emission-reduction.
Non-air throttle engine control gear of the present invention, constitute by camshaft, valve seat, mobile mechanism, camshaft is connected with cylinder head or cylinder block with bearing by bearing, be connected with mobile mechanism on the camshaft, camshaft one end is connected with camshaft gear wheel or belt pulley center spline by spline, one side of the cam on the camshaft is the inclined-plane, and the valve seat bottom contacts with cam of camshaft inclined-plane.
Described mobile mechanism is a kind of in sliding sleeve, slip ring, the chute.Described mobile mechanism is a kind of in hydraulic pressure, motor, air pressure, vacuum or the mechanical pushing device.
Be connected with tooth bar on the described sliding sleeve, the gear engagement that connects on the rack and pinion axle.Be connected with shift fork on described slip ring, the chute.
It is the inclined-plane that described valve seat bottom contacts a side with cam of camshaft inclined-plane.Described cam of camshaft inclined-plane and horizontal angle and valve seat inclined-plane and horizontal corner dimension are consistent.
Motor is clockwise or be rotated counterclockwise down by hydraulic coupling, mechanical force and electronic signal control for described gear.
Non-air throttle engine control gear of the present invention, camshaft is connected with cylinder head by the bearing hole on the cylinder head, or be connected with cylinder block by the bearing hole in the cylinder block and all can, be connected with mobile mechanism on the camshaft, when mobile mechanism is sliding sleeve, on the sliding sleeve, be connected with tooth bar, the gear engagement that connects on the rack and pinion axle, gear descends clockwise or is rotated counterclockwise by the effect of external force such as hydraulic coupling, mechanical force and electronic signal control motor, thereby drives the camshaft horizontal motion; When mobile mechanism is slip ring or chute, be connected with shift fork on slip ring or the chute, shift fork is stirred slip ring or chute, thereby drives the camshaft horizontal motion.When mobile mechanism is that one in hydraulic pressure, motor, air pressure, the vacuum pushing device advances, camshaft is realized horizontal motion under the effect of external force.When camshaft when the valve seat direction is moved, cam of camshaft inclined-plane is with valve seat jack-up, along with the inclined-plane of camshaft is more and more higher, valve seat is also more and more higher by the position of jack-up, thereby make the gas that enters in the cylinder also more and more, then power is big more, and rotating speed is also high more.The bottom of valve seat can also be that part is the structure on inclined-plane for planar section, and the planar section of valve seat bottom contacts with camshaft when idling, the smooth working when this helps engine idle, and valve seat contacts with camshaft with the inclined-plane when motor quickens.The gear shaft that drives sliding sleeve with external force is equivalent to the throttle plate pin of former closure control motor, owing to cancelled closure, air-flow can flow in suction tude freely and smoothly, has improved the charging efficiency of every cylinder, has reduced fuel consume, has reduced discharging.The reactivity of motor and smooth-going power output have been improved.
