Abstract

The following invention relates to an ignition coil assembly for an ignition system comprising an ignition coil where said assembly has a main axis and is configured for insertion into and / or removal out of a well associated with an internal combustion engine, wherein the assembly comprises an elongated extension body made of flexible material, said extension body comprising an upper end portion and a lower end portion wherein the extension body is arranged to be transversally bendable in relation to the main axis so that the upper end portion and the lower end portion may assume an angle (alpha) in relation to each other.

Description

technical field [0001] The present invention relates to an ignition coil assembly for a spark ignition internal combustion engine comprising an ignition coil, wherein the assembly has a major axis and is configured to be inserted into a spark plug recess. Background technique [0002] Internal combustion engines include spark plugs for initiating combustion that drives the engine pistons and require the spark to ignite the compressed fuel. Traditionally, the ignition coil turns the low voltage from the battery into the high voltage needed to create an electrical spark in the spark plug to ignite the fuel. Common to all spark plugs is that they are arranged to fit in a recess on the cylinder head which pierces the side wall of the combustion chamber so that the ignition terminal comes into contact with the interior of the combustion cylinder. Direct ignition systems, where the ignition coil is mounted directly over each spark plug, are known to be advantageous because they e...
