Installation device for engine ignition system and engine with same

Abstract

The invention discloses an engine ignition system mounting device. The engine ignition system mounting device comprises a spacing cover for covering a spark plug and a high-pressure ignition harness; a connecting part for connecting with a cylinder cover is arranged at the bottom end of the spacing cover, and an end sealing ring coats the top end; the end sealing ring includes an annular first sealing part and an annular second sealing part; the first sealing part is provided with a sealing lip; an elastic part for pressing the sealing lip in the radial direction of the spacing cover is arranged out of the sealing lip; and the top surface of the second sealing part is bonded with a connecting end surface, for connecting with a cylinder cover shell, of the high-pressure ignition harness, and the bottom surface is bonded with an end surface, opposite to the connecting end surface, in a cylinder cover shell harness hole. The engine ignition system mounting device, provided by the invention, effectively realizes the surrounding sealing of the spark plug to isolate the contact with a medium, guarantees normal ignition work of the spark plug, and improves the engine reliability. The invention further discloses an engine comprising the engine ignition system mounting device.

Description

Technical field [0001] The present invention relates to the technical field of engines, and more specifically, to an engine ignition system mounting device, and also to an engine including the above engine ignition system mounting device. Background technique [0002] The engine is the power component of the vehicle, and its working state directly affects the performance of the vehicle. The ignition system is an important part of the gasoline engine. The performance of the ignition system has a great impact on the engine's power, fuel consumption and exhaust pollution. Ignition system generally refers to all equipment that can generate electric sparks between the two electrodes of the spark plug, usually composed of batteries, generators, distributors, ignition coils and spark plugs. [0003] At present, for natural gas engines, in-cylinder ignition systems are mostly used, and high-voltage pulses need to be transmitted to spark plugs, so that the spark plugs ignite the mixture in...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the first object of the present invention is to provide an engine ignition system installation device. The structural design of the engine ignition system installation device can effectively solve the problem of poor sealing effect of the spark plug, which is difficult to be isolated from the medium, and thus causes abnormal ignition of the spark plug. , the second object of the present invention is to provide a kind of engine that comprises above-mentioned engine ignition system installation device
