While he wasn't a natural teacher when he started, he worked hard and kept trying new things. The connecting rod is coupled to the piston by a tube called a wrist pin. A1: The automobile engineering degree is a four-year engineering degree (BE or B.Tech) course. (15) Answer: Option D. Practice Test: Question Set - 07 1. The advantage of having separate camshafts is that each cam can be placed very close to the valve, allowing the cam’s lobes to either work directly on the valves or through a very small rocker arm. Other manufacturers cast lightweight aluminum blocks for weight reduction. Practice Test: Question Set - 01 1. Most job opportunities require formal training in automotive technology in high school or a postsecondary school or college. There is also a corrugated ring, known as the oil ring, which allows oil to lubricate the cylinder walls so that the piston, rings and cylinders do not wear prematurely.

We’ll tell you all about the noisy chunk of metal connected to your wheels and a little bit about the things that make it go forward. Please try again. The block also has a number of fluid passageways cast into it. The rings act as a seal that keep the cylinder pressure from the combusted air and fuel mixture between the head and top of the cylinder, ensuring the pressure pushes the piston down instead of pushing past it. Similarly, when one piston is pushed down by the air/fuel combustion, it turns the crank and pushes another piston up, ready for the next combustion. A 4-stroke refers to the four strokes in the power cycle; the intake stroke, the compression stroke, the power stroke and the exhaust stroke. Some camshaft lobes push directly on the valves to open them, but most street-driven car engines work indirectly through a rocker arm.
