Although diesels emit less greenhouse gasses there are serious concerns about the public health effects of their PM emissions. The central question is therefore which pollutants are more important. This type of question is usually addressed by calculations of external costs, but the answers are ...
Steady ignition demands more compression, which produces more heat and, therefore, a greater capability to do work. The steady ignition has another advantage: it ensures the fuel is leveraged. The amount of chemical energy converted into mechanical energy by a diesel engine is far greater than th...
Answer (1 of 2): Modern diesel engines are now as quiet as petrol engined vehicles.However, it is true to say that older types of diesel engines were much noisier, and together with low power outputs, was one of the reasons they were usually only fitted
One of the many choices you have to make when buying a 4WDrive is whether to have a diesel or petrol engine. There is a lot of folklore and myth that a "real" 4WDrive HAS to be a diesel, but there are some good arguments for a petrol engine. Now, before any diehard 4WDriver ...
“Unsurprisingly people with diesels have been doing most mileage, probably seeking better long-distance fuel economy, but this study is also evidence that battery-electric powered cars are not just trophy vehicles signalling their owners' green credentials but prior...

Almost half (47%1) of European ICE drivers say the main advantage of a petrol or diesel car is greater range autonomy. Likewise, when looking into the reasons behind the 30%1 of European ICE drivers who are unlikely to consider a fully electric vehicle, the major...
These are also the most efficient diesel cars. 10. Which petrol car has the best mileage in India? A highlight of the Maruti Suzuki Ignis is the peppy 83hp, 1.2 liter K12M petrol engine, which delivers an ARAI-rated efficiency of 20.89kpl in manual and AMT automatic form. 11. Which ...
Petrol and diesel (柴油)cars may still dominate our roads, but their days are numbered. A recent university study found that current electric cars could be used for 87 per cent of daily car journeys in the US. That figure could rise to 98 per cent by 2020. ...
A little over a year ago, I stuck my neck out to suggest that theBMW 8-series works better with a diesel inline-six than a petrol V8. Today, I’d once again like to get into the 8er diesel vs petrol debate, but don’t panic - this isn’t a case of Morpheus-troubling...
