▶︎ PETROL vs DIESEL Engines - Every Differences Explained
▶︎ In this video, we dive into a detailed comparison of petrol (spark ignition) and diesel (compression ignition) engines. We cover the key differences in combustion processes, why diesel engines don't rev as high, and topics like compression ratios, power, torque, efficiency, emissions, and driving enjoyment.
▶︎ While petrol and diesel engines share a similar structure as internal combustion engines, their combustion methods differ. Petrol engines rely on a spark to ignite the fuel-air mixture, while diesel engines use heat from compressed air, which allows for higher compression ratios and greater efficiency. However, this also leads to increased cylinder pressure and limits how high diesel engines can rev.
▶︎ Diesels are known for their efficiency, thanks to higher compression ratios, leaner fuel mixtures, and fuel density. Emission-wise, both engines have their pros and cons, with modern diesel engines incorporating technology like diesel particulate filters and exhaust fluid injection to reduce pollutants. However, maintenance issues in the second-hand market can lead to increased pollution over time.
▶︎ When it comes to fun, both engine types offer different thrills. Petrol engines provide high-revving excitement and sound, while diesel engines deliver addictive low-end torque.
▶︎ Dual-Fuel Engines:
● Dual-fuel engines combine the best of both diesel and gas engines. These engines typically use diesel as a pilot fuel to ignite a secondary fuel, such as natural gas. This combination allows for flexibility in fuel usage, enhanced efficiency, and reduced emissions, making them popular in applications where environmental and operational costs are key concerns. By optimizing the combustion process with two fuel sources, dual-fuel engines provide improved performance and adaptability across various load conditions.
