Motoring: Why motorists are ditching petrol cars for LPG cars

The combustion process of an LPG occurs after the gas has vaporized; it is then mixed with air in the engine's combustion chamber.

The air-fuel mixture is then ignited by the spark plugs to generate power and propel the vehicle.

Alex Mwita, one of the motorists whose car was being worked on told The Standard that it was his second vehicle to go through the modification.

However, he warns that it requires a proper engine management system.

"I operate Bolt and I have since saved a lot on fuel and hence able to even buy another car to supplement my business. However, it is key to note that LPG cars are equipped with sensors that monitor various parameters, such as the air-fuel mixture, temperature, and pressure. This system adjusts the fuel injection and other engine parameters to ensure efficient combustion and optimal performance. Once they fail, you can't move," Mwita advised.

According to the mechanic, LPG has a higher octane rating than petrol, and it typically has a higher energy content. This means that LPG can result in more efficient combustion in the engine, potentially providing better fuel efficiency and, consequently, cost savings.

It is key to note that before deciding to switch to LPG, it's advisable to conduct a thorough analysis based on your specific driving patterns, local fuel prices, conversion costs, availability of LPG stations in your locality, and overall cost-effectiveness of using LPG compared to petrol.
