Owing to these factors, diesel engines deliver better mileage than gas engines. Diesel engines emit minimal amounts of greenhouse gases such as carbon monoxide that lead to global warming. Still, they emit relatively high amounts of soot and nitrogen compounds that cause acid rain and other issues.
Both diesel and gas engines are internal combustion engines that convert fuel into energy. Combustion allows the machines to work in a series of small explosions and this is where the two engines differ.
Gas engines operate when fuel is mixed with air, then compressed by pistons and ignited by spark plugs. Diesel engines compress the air before injecting the fuel directly into the combustion chamber. Air heats up when it’s compressed, so the fuel in diesel engines ignites without the use of sparks—our diesel engine services in Calgary including this kind of direct injection.
