How to Distinguish the Camshaft of a Mondeo?

[DeCorey]

The distinction of the Mondeo camshaft is that the intake is indicated by the letter I, and the exhaust is indicated by the letter E. The function of the car camshaft is to control the opening and closing of the valves. The camshaft is usually forged from high-quality carbon steel or alloy steel, and can also be cast from alloy cast iron or ductile iron. The journal and cam working surfaces are polished after heat treatment. The symptoms of a damaged car camshaft are as follows: 1. The car has a high-voltage spark, but it takes a long time to start, and the car can eventually run; 2. During the starting process, there will be a phenomenon of crankshaft reversal, and the intake manifold will backfire; 3. The car idles unstably, with severe shaking, similar to a car misfiring; 4. The car lacks acceleration and cannot run, with the RPM exceeding 2500; 5. The vehicle has high fuel consumption, excessive exhaust emissions, and the exhaust pipe produces black smoke.
