Description

TITLE OF THE INVENTION:AN INTERNAL COMBUSTION ENGINE FOR A VEHICLETECHNICAL FIELD

[0001] The present invention relates to a vehicle. More particularly, the present invention relates to an internal combustion engine for a vehicle.BACKGROUND

[0002] Typically, an internal combustion engine is used for powering a vehicle. The internal combustion engine includes a piston and cylinder arrangement for combusting fuel thereby driving the crankshaft for facilitating movement of the vehicle. The fuel is combusted in the combustion chamber in the cylinder head during the compression stroke of the piston.

[0003] In addition, a spark is a vital component in the internal combustion engines, responsible for igniting the compressed air-fuel mixture by producing a high-voltage spark in the combustion chamber. This ignition process powers the IC engine by triggering combustion. Additionally, the spark plug helps dissipate heat from the combustion chamber to the engine’s cooling system, preventing overheating and ensuring efficient operation. Without a well-functioning spark plug, engine performance can suffer, leading to misfires or failure to start. A cylindrical hole is usually provided inside the cylinder head assembly of the internal combustion engine for mounting the spark plug unit including the spark plug and the ignition system. The cylindrical hole is extended along the length of the cylinder head in the cylinder head and the cylinder head cover. Generally, the cylindrical hole in the cylinder head assembly is covered through a seal / cap from outside. The cap is provided for enclosing the hole / cavity on the cylinder head cover to prevent inlet of impurities into the cavity. However, during usage of the vehicle, impurities seep inside hole / cavity through gaps between the cap / seal and the surface of the cylinder head cover and gets accumulated in the cavity around the around the spark plug.

[0004] In addition, during servicing of the vehicle’s engine when the cap of the cylindrical hole is removed, there are chances that dust, water and other fluids can enter into the cylindrical hole and gets accumulated in the cylindrical hole around the spark plug. Hence, to drain the accumulated fluids or dust in the cylindrical hole around the spark plug, adrain bore is configured to extend from the cylindrical hole to an outer surface of the cylinder head. The drain bore forms an outlet opening on the outer surface for draining the accumulated fluids or mist from the cylinder head to maintain the operation of the spark plug. However, the outlet opening of the drain bore provided on the side surface of the cylinder head allows entry of the external fluid into the cylindrical bore surrounding the spark plug. Moreover, in scenarios such as washing of the vehicles, there are higher chances of water entering into the cylindrical hole around the spark plug. This accumulation of water can hinder with the operation of the spark plug thereby preventing start of the vehicle and sometimes leading to switch off of the engine.

[0005] In view of the foregoing, it is desirable to overcome at least the above-mentioned disadvantages of the IC engine of the vehicle and to provide an internal combustion engine which is configured to overcome the above disadvantages.

[0006] Further limitations and disadvantages of conventional and traditional approaches will become apparent to one skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.SUMMARY OF THE INVENTION
