Is TDI better than petrol?
As mentioned before, Diesel is 20% more efficient than gasoline. Its thicker density allows it to produce more energy with less amount of fuel. Also, a Diesel engine can have the same amount of power as gas but at a lower RPM. In other words, a slower rate of burning fuel for the same output. Diesel engines are particularly vulnerable to poor fuel quality, restricted airflow and cooling system inefficiencies. Because they rely on high compression and precise fuel injection, even minor contamination or injector clogging can cause significant performance issues.Diesel Cons: Abysmal horsepower, slower speed. Expensive fuel, limited gas stations with diesel. Noisier and more rugged ride than gasoline-powered engines. Produce emissions that emit carcinogens, nitrous oxides, and soot into the atmosphere.Higher NOx emissions: Diesel fuel produces higher emissions of nitrogen oxides (NOx) and particulate matter than petrol fuel. These pollutants can contribute significantly to air pollution and have adverse health effects. Higher cost: Diesel fuel is often more expensive than petrol fuel, particularly in urban areas.Diesel cars only make more sense than petrols if you are doing higher than average mileage – around 12,000 miles. Older diesels are more polluting than newer ones, too, and are subject to penalty charges or fines if they enter certain cities.
Which is better, TDI or CRDi?
Common rail diesel fuel systems have better fuel efficiency and performance than direct injection. This is because CRDi systems allow for multiple fuel injections per engine cycle. Since fuel is delivered to the individual injectors, CRDi maintains fuel at a consistent pressure, improving fuel efficiency. Diesel common rail direct injection (CRDI) and its benefits. Common rail is a fuel injection system found in modern diesel engines.
