The first overhead valve (OHV) engine was invented by the American engineer and inventor, Charles Kettering, in the early 1900s. Kettering's design was utilized in the 1914 Cadillac, which featured a V8 engine with overhead valves, marking a significant advancement in automotive engineering. This design improved engine efficiency and performance, leading to its widespread adoption in later vehicles.

What are the valve specifications for a 20 HP twin Briggs and stratton engine?
For a 20 HP twin Briggs & Stratton engine, the valve specifications typically include a valve clearance of around 0.005 to 0.007 inches for the intake and 0.007 to 0.009 inches for the exhaust valves when cold. The engine usually features a flathead or overhead valve design, with both intake and exhaust valves made from durable materials to withstand high temperatures. Specific dimensions and tolerances can vary by model, so it's essential to refer to the engine's service manual for precise specifications.
Why do we use throttle valve in steam engines?
For a steam engine, the steam(throttle) valve that sets the engine speed/power is often known as a regulator. k.Shiva
What is valve lag on a engine?
Valve lag in an engine refers to the delay in the opening and closing of the engine's intake and exhaust valves relative to the position of the piston. This lag can affect engine performance, efficiency, and emissions, as it can lead to suboptimal air-fuel mixture intake and exhaust gas expulsion. In high-performance engines, managing valve timing through advanced technologies like variable valve timing (VVT) helps reduce valve lag, optimizing power delivery across different RPM ranges. Proper tuning of valve timing is crucial for achieving peak engine performance.

What is difference between overhead valve engine and overhead cam engine?
Mainly, the difference is that in an overhead cam engine, the camshaft is mounted on the head of the engine, and the valves are still overhead, in an overhead valve engine (sometimes called a "pushrod motor"), the camshaft is in the crankcase.

Does a 1988 Cadillac DeVille have a northstar engine?
No it does not. The only engine in the 1988 Cadillac De Ville was the 4.5 Digital fuel injected engine. The 4.5 engine is a 2 valve per cylinder overhead valve (not overhead cam) engine. It was a good engine but not in the power category as the Northstar.
How do you run overhead on a 3126 caterpillar?
