Problems solved by technology
The concept of variable compression ratio has been around for a long time, but there are very few such engines in the market, which also shows that although variable compression ratio engines are good, their feasibility is poor and there are many problems : Such as complex structure, difficult control, insufficient adjustment, heavy weight, large volume, high cost, short life, poor implementability, unstable performance and difficult inspection and maintenance, etc., resulting in variable compression ratio engines. Slow progress in research and development

Embodiment Construction
[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as Figure 1 to Figure 8 As shown, an electronically controlled eccentric gear type variable compression ratio engine of the present invention includes a cylinder block 1, a piston 2, a connecting rod 4, a crankshaft 5, a crankshaft pulley 10, a brush bracket 14, a conductive slip ring seat, and an eccentric gear 7 With regulating motor 9, other parts are identical with other motors.
[0031] The inside of the front end of the crankshaft pulley 10 is equipped with a conductive slip ring seat. The conductive slip ring seat includes a slip ring 13 and a base 12. The slip ring 13 and the base 12 are insulated from each other. The base 12 is installed and fixed in the front groove of the crankshaft pulley 10. The slip ring 13 The slip ring 13 is in electrical contact with the brushes on the brush holder 14 and the wire 11 is ...

The invention discloses an electronically controlled eccentric gear type variable compression ratio engine, which comprises a cylinder body and a piston located inside the cylinder body, the piston pin of the piston is connected with the small end of the connecting rod, the large end of the connecting rod is connected with the crankshaft, and the The crankshaft pulley is arranged at the front end, and the big end of the connecting rod is eccentrically connected with the crankshaft through an eccentric gear, which includes a gear and an eccentric wheel. The conductive slip ring seat arranged at the front end of the crankshaft pulley is electrically connected, and the conductive slip ring seat is electrically connected with the adjusting motor arranged on the crankshaft crank through a wire, and the gear of the adjusting motor is coupled with the gear of the eccentric gear arranged on the connecting rod neck of the crankshaft. The eccentric wheel of the eccentric gear cooperates with the large end of the connecting rod. The invention controls the operation of the eccentric gear by adjusting the motor to change the compression ratio, and has the characteristics of simple structure, easy realization, stable performance, low cost, wide application range and remarkable fuel-saving effect.
Description
technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an electronically controlled eccentric gear type variable compression ratio engine. Background technique [0002] At present, research on engines with variable compression ratios is an important research direction in the field of internal combustion engine technology. When the internal combustion engine is running at medium and low speeds, due to the small intake air volume or fuel injection volume, the maximum pressure or temperature in the compression stroke or power stroke is relatively low, so a higher compression ratio is suitable; when the internal combustion engine is running at medium and high speeds, the intake air volume or The fuel injection volume is large, and the maximum pressure or temperature in the compression stroke or power stroke is relatively high, so it is suitable to adopt a lower compression ratio, which can greatly improve the efficien...
