Abstract
The invention provides variable compression ratio of engines, which belongs to mechanical and hydraulic systems. The invention mainly solves the problem of allowing the compression ratio of engines to be adjustable. An adjustment method mainly comprises the steps of controlling hydraulic systems, screw rods and parts with inclined planes through a control mechanism and controlling the upward/downward movement of an inner-cylinder cover assembly in order to change the position of a piston in a top dead center, and then the compression ratio can be changed. The variable compression ratio has the advantages of enabling the engines to adapt to the use of various fuels and ensuring no decrease in power, along with better economical efficiency and more reduction in emission.
Description
Technical field:
Machinery and hydraulic system;
Background technique:
Current China also has no talent or the information of unit application " engine variable compression ratio ";
Summary of the invention:
By the change in location of adjusting inner cylinder body cylinder cap assembly, thereby change combustion chamber volume, reach the variation of compression ratio; The way of regulating and overcoming the explosive force influence is exactly by hydraulic mechanism, screw rod, has the part on inclined-plane.When regulating, camshaft location will change, and for this reason, has designed and does not change bent axle and the distribution device of camshaft speed than (two-to-one).Designed control mechanism to controlling mechanism.
Claims (3)
- The major character of " motor change compression ratio " is that the engine compresses specific energy changes as required, thereby the art of wanting that can adapt to each fuel, guarantee the requirement of power character Economy discharging, even send at motor under the situation of onesize power, can reduce fuel quantity and discharging.1, it is variable and can overcome the left and right sides spiral of the power of combustion mixture detonation, the part with inclined-plane or hydraulic mechanism that the relative piston of inner cylinder body cylinder cap assembly combustion chamber volume when top dead center is directly regulated in protection; Protect inner cylinder body cylinder cap structural design simultaneously;
- 2, protection control mechanism or hydraulic mechanism can make controlling mechanism motion adjusting inner cylinder body cylinder cap assembly move up and down and can overcome detonation power;
- 3, camshaft is when mobile, because of crank position is constant, for guaranteeing that the constant and bent axle of port timing and camshaft speed are than (two-to-one) constant designed distribution device;
