What does H-type engine mean?

[ZoeyRose]

H-type engine, also known as a horizontally opposed engine, is a type of V-engine where the angle of the V is extended to 180°, positioning adjacent cylinders opposite each other, hence forming a horizontally opposed engine. It is typically configured with 4 or 6 cylinders. Below are the advantages and disadvantages of the H-type engine: 1. Advantages: Low center of gravity and low vibration. The overall height of the horizontally opposed engine is significantly reduced, and its length is shortened, making the engine appear flatter and more compact. The direct benefit is a lower vehicle center of gravity, resulting in smoother driving, enhanced agility, and reduced risk of rollover. 2. Disadvantages: High manufacturing cost and excessive engine width.
