Motorcycle difficulty in starting when cold but normal when hot is due to insufficient compression ratio in the cylinder or poor valve sealing. The cylinder is a cylindrical chamber within the engine, containing a piston driven by the pressure or expansion force of the working fluid. Some special types of engines may have similar but non-cylindrical components. Below is an extended introduction: Valve function: The valve is specifically responsible for introducing air into the engine and expelling exhaust gases after combustion. Structurally, it is divided into intake and exhaust valves. Motorcycle introduction: A motorcycle is a two- or three-wheeled vehicle driven by a gasoline engine, steered by handlebars, known for its lightweight, flexibility, and rapid movement. It is widely used for patrol, passenger and cargo transportation, and also serves as sports equipment.

What is the difference between 10w40 and 10w50?

10w40 and 10w50 have the following differences: 1. Different viscosity: 40 represents the viscosity. The larger the number, the higher the viscosity and the higher the maximum applicable temperature. 2. Different vehicle attributes. 3. Different fluidity: The number before W represents the minimum temperature it can withstand. The smaller the number before W, the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the minimum applicable temperature. 4. Different environmental temperatures: Compared with 10w50, engine oil 10w40 can adapt to lower minimum temperatures. Engine oil with a lower value before W can start the engine more easily in cold weather.

How to Identify the Model of an Oil Filter?

You can check the model of an oil filter on its housing, as it usually carries the manufacturer's part number. Each manufacturer has its own unique coding system, and the identification can be done in the following ways: 1. Oil filters typically start with 'JX' to indicate their type. The following numbers can help determine the appropriate filter model for the vehicle. 2. Original equipment manufacturer (OEM) oil filters and aftermarket filters have different coding systems. OEM filters usually do not include 'JX' and may consist entirely of numbers or letters. In such cases, use calipers to measure the thread size and sealing ring dimensions to select the correct filter. 3. There are many models of oil filters, as each vehicle model requires a different filter. Examples include screw-type air compressor oil filters, WK962/7, WK940/20, and others.
