Adjustable spark plug installation structure for hybrid vehicles

Abstract

The invention discloses an adjustable spark plug installation structure for a hybrid vehicle, which includes a cylinder head and a spark plug. A mounting seat is installed on the cylinder head in the form of a ball hinge. The mounting seat is provided with a mounting hole, and the spark plug can be moved up and down. Movably installed in the mounting hole, the lower end of the spark plug passes through the mounting hole and is located in the combustion chamber, a lifting mechanism for driving the spark plug to move up and down is provided between the upper end and the mounting seat, and a lifting mechanism for driving the mounting seat is provided between the mounting seat and the cylinder head yaw drive mechanism. The beneficial effect of the invention is that the ignition position of the spark plug can be adjusted in real time according to the operating conditions of the engine, so as to improve the fuel efficiency.

Description

technical field [0001] The invention belongs to the technical field of engines, and in particular relates to an adjustable spark plug installation structure for a hybrid vehicle. Background technique [0002] The spark plug is a part of the fuel engine that introduces high-voltage current into the cylinder to generate electric sparks to ignite the combustible mixture. [0003] When the engine is working, the mixed oil and gas enters the combustion chamber through the intake port. According to the working sequence of the engine, the spark plug detonates the mixed oil and gas in the combustion chamber at an appropriate time to push the piston to do work. [0004] The fuel efficiency not only seriously affects the power, economy and emission performance of the engine, but also determines whether the engine can work normally. The ignition timing, ignition position and ignition energy of the spark plug are closely related to the combustion efficiency. The ignition timing Too ear...

AI Technical Summary

Problems solved by technology

[0004] The fuel efficiency not only seriously affects the power, economy and emission performance of the engine, but also determines whether the engine can work normally. The ignition timing, ignition position and ignition energy of the spark plug are closely related to the combustion efficiency. The ignition timing Too early can easily lead to engine knocking, resulting in damage to parts, too late can easily lead to power loss and increased fuel consumption, and insufficient ignition energy can easily lead to engine work difficulties, especially for hybrid vehicles, the engine requirements are more stringent, more flexible, and more efficient. Diversity

[0005] In the existing technology, there are many applications of control mechanisms and systems on the ignition timing and ignition position of spark plugs, and certain technological breakthroughs have been made, but there are still relatively few studies on improving fuel efficiency by controlling the ignition position
