What is DOHC?
1 Answers
DOHC (Double Overhead Camshaft) refers to dual overhead camshafts in Chinese. More details about dual overhead camshafts are as follows: 1. Function: Dual camshafts can adjust valve overlap angle, thereby delivering greater horsepower. However, they tend to produce insufficient torque at low RPMs and may pose certain maintenance difficulties due to their complex mechanical structure. 2. Origin: The dual camshaft technology originates from racing cars, primarily designed to control the timing difference between intake and exhaust valves.
