Adjustable spark plug mounting structure for hybrid electric vehicle

Abstract

The invention discloses an adjustable spark plug mounting structure for a hybrid electric vehicle. The mounting structure comprises a cylinder cover and a spark plug, a mounting seat is mounted on thecylinder cover in a spherical hinge manner, a mounting hole is formed in the mounting seat, the spark plug is mounted in the mounting hole in an up-and-down moving manner, the lower end of the sparkplug penetrates through the mounting hole and is positioned in the combustion chamber, a lifting mechanism for driving the spark plug to move up and down is arranged between the upper end of the sparkplug and the mounting seat, and a driving mechanism for driving the mounting seat to deflect is arranged between the mounting seat and the cylinder cover. The mounting structure has the beneficial effects that the ignition position of the spark plug can be adjusted in real time according to the use working condition of an 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
