Description

TITLE OF INVENTION:A POWER UNIT TECHNICAL FIELD

[0001] The present subject matter relates to a power unit, more particularly relates to the power unit for a vehicle.BACKGROUND

[0002] Typically, original equipment manufacturers (OEMs) tend to improve the overall performance of a vehicle. The overall performance of the vehicle is dependent on a power source efficiency. Importantly, the power source efficiency is directly dependent on some of the factors such as compression ratio, air fuel ratio, parameters of engine design, thermal management, turbocharging and supercharging, and lubrication.

[0003] It is observed that without proper lubrication, the power source can face several severe problems such as increased friction and wear which is due to metal-to-metal contact, overheating because of a greater number of moving parts, corrosion and rust, contamination and sludge build-up, issue of noise vibration and homologation, and many more.

[0004] Generally, the power source such as an internal combustion engine include a cylinder head. The cylinder head of the power source has multiple moving parts such as intake and exhaust valves, valve springs, camshaft (s), rocker arms, tappet (s), pushrod (s), timing chain, variable valve timing components, and a like. Theseparts requires sufficient supply of a lubrication oil which can be mineral oil, synthetic oil, semi-synthetic oil and a like for smooth functioning.

[0005] The lubrication oil is supplied through various integral passages and passes through multiple components which carries the risks such as loss of pressure and insufficient supply due to blockages. Thus, it is critical to ensure the flow of oil is proper and to all the components. One known solution to check the pressure of lubrication oil reaching the cylinder for lubricating the components of the engine is to keep check pressure of the flow of lubricating oil in the cylinder head.

[0006] In addition, there are several challenges to accommodate a sensing unit on the engine for sensing pressure of the lubricating oil such as but not limited to packaging space in the vehicle as less space is available for packaging components on the engine’s cylinder head of the two wheeled vehicle without increasing the engine size, and environmental challenge which are due to the high temperature around the cylinder head, and vibration and mechanical shocks. In addition, connection requirement: as the sensing unit is connected with an electronic control unit so to maintain the constant connection location of sensing unit becomes a challenge. Serving and assembly issue: placement of the sensing unit at a certain location on the engine which provides ease of accessibility of servicing and assembly is also challenge due to packaging constrain and vehicle layouts of the two wheeled vehicle having less packaging space and several parts. Further the OEMs always tries to decrease the assembly time of components, for that the location and mounting of the sensing unit becomes crucial.

[0007] Therefore, it is needed to provide a solution which solves at least one above-mentioned problems.SUMMARY
