AI Technical Summary

Problems solved by technology

When the throttle valve is opened and closed, it will cause the engine air intake pump and throttle loss to easily generate turbulence, which will affect the smooth flow of air in the intake pipe, resulting in poor engine inflation, especially affecting the intake of each cylinder for multi-cylinder engines. Inhomogeneous gas volume, low inflation efficiency, incomplete combustion, thus affecting engine power, fuel economy and large emission pollution and other defects

Embodiment 1

[0015] Such as figure 1 with figure 2 As shown, the throttleless engine control device of the present invention is composed of a camshaft 1, a valve seat 3, and a moving mechanism. The camshaft 1 is connected to the cylinder head 14 or cylinder block 15 through bearings and supports 2, 5, and 8 The camshaft 1 is connected with a moving mechanism. One end of the camshaft 1 is connected with the central spline groove 16 of the camshaft gear or pulley 9 through a spline 10. There is at least one cam 4 with a bevel on the camshaft 1. One side of the cam 4 is inclined, the bottom of the valve seat 3 is in contact with the camshaft 1 and the cam 4 is inclined. The moving mechanism is the sliding sleeve 6. The sliding sleeve 6 is connected with a rack 11, and the rack 11 is connected to the gear shaft 12 13 is engaged, the sliding sleeve 6 is connected with a sliding sleeve jacket 7, and the gear 13 is controlled by hydraulic pressure, mechanical force and electronic signals to rotat...

Embodiment 2

[0017] In the throttleless engine control device of the present invention, the moving mechanism is one of a slip ring and a sliding groove, and a shift fork is connected to the sliding ring or the sliding groove. The rest is the same as in Example 1.

Embodiment 3

[0019] In the throttleless engine control device of the present invention, the moving mechanism is one of hydraulic, electric, pneumatic, vacuum or mechanical pushing devices. The rest is the same as in Example 1.

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 [0001] The invention relates to an engine control device, in particular to an engine device that has no throttle and can accurately control the size of the engine air intake. Background technique [0002] The original engine camshaft only controls the engine valve lift, and cannot adjust the engine speed and power. The engine speed and power must be adjusted by the throttle installed on the engine's intake pipe to achieve the engine speed and output power. The opening and closing process of the throttle valve will cause the engine suction pump and throttle loss to easily produce turbulence, which will affect the smooth flow of airflow in the intake pipe, resulting in poor engine inflation, especially affecting the intake of each cylinder in a multi-cylinder engine. Uneven air volume, low charging efficiency, and incomplete combustion, which affect engine power, fuel economy, and large emissions pollution. Summary of the invention [0003] The purpose of the presen...
