A Petrol contributes more towards the formation of acid rain. B Carbon monoxide is produced by complete combustion of the fuels. C All the pollutants listed can be removed by installing a catalytic converter. D The temperature in the petrol engine is lower than that in the diesel engine. ...
根据第一段“Vehicles on our roads are now mostly petrol and diesel (柴油) cars, but their days cannot continue for much longer. A recent university study found that current electric cars could be used for 87 percent of daily car journeys in the US. That figure could rise to 98 percent ...
Diesel and petrol are both obtained from crude oil, but diesel is more efficient and suitable for steady motion because it is denser and ignites more slowly than petrol. Diesel engines are also sturdier and heavier than petrol engines, but they require more maintenance. Both petrol and diesel f...

Not only is this more energy-efficient, but it also reduces wear and tear on the brakes. But crucially, electric car drive trains have significantly fewer moving parts than engines found in petrol or diesel cars. As a result, EVs lose far less energy via heat or friction between parts. ...

C 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% of daily car journeys in the US. That figure rose to 98% in 2020.One hurdle to the widespread adoption of electric...
The reason PHEV’s get bad press is because they have an engine, almost without exception one that runs on petrol and, with the best will in the world, they are not as efficient as diesel But diesel is the bad boy now, isn’t it? Well, the latest diesel engines conforming ...
In addition to the far greater increase in thermal efficiency compared to the diesel engine, the gasoline engine also benefits from the H/C ratio, which is more advantageous for petrol than for diesel fuel. The CNG engine has the lowest CO2-emission. The combination of the 100 kW gasoline ...
56% think they are more expensive to buy than their petrol/diesel equivalent 48% suggest there is not enough public charging infrastructure. However, over a quarter of EV motorists say that running out of charge (28%), charging time (30%) and EVs being expensive (31%) are...
