How to Increase the Efficiency of a Petrol Engine
The efficiency of a petrol engine is determined by its total power output, which is proportional to its pumping loss. Generally, pumps require 20% of the engine’s total power production to produce rated power. However, the pumping losses are minimal at low speeds. The pumping loss increases with speed. Hence, engines should not be driven below their rated power. The following are some of the factors that contribute to the efficiency of a petrol engine.
Fuel-lean running
When your engine is running lean, you are making it work harder than it should. This results in a reduced power output, difficult starting and increased gas consumption. Left unchecked, this problem can cause irreparable damage to your engine. A fuel- lean problem can also be the cause of your car’s Check Engine Light. Below are a few common symptoms of a fuel-lean condition.
A faulty fuel pump, a clogged fuel filter, or …
