All the engines have hydraulic valve lifters in one form or another. The most common types of engine that has them is your vehicle engine. They created to get rid of the need for combustion engines to have mechanical clearance in the engine valve train.
The reason that clearance is required is to keep the valve from being held open and destroyed as the valve train goes through its process of thermal expansion. In in effect, hydraulic valve lifters keep the valve healthy and protected from an engine normal thermal expansion process.
