I’m interested in the history of the diesel engine and believe that in general terms it is the best option in the modern car.
Diesel engines today are often more powerful, economical, cleaner and durable than their petrol (gas) counterparts. The big players out there are moving ahead with diesel – even Jaguar have gone diesel:
“The new 2.0 litre diesel engine offers petrol-engine levels of refinement and everyday driveability.
"Delivering low noise and strong performance – a maximum speed of 125mph and 0-62mph in just 9.9 seconds – the X-TYPE 2.0D is even more notable for mile-eating cross-country ability.
"The Common Rail Fuel System is designed for high-speed diesel injection engines. Some of the benefits are as follows: Extended injection periods send more fuel to the cylinders, resulting in increased engine power and lower bottom-end torque around 1,800 rpm. Noise Reduction Technology makes the X-TYPE Diesel engine incredibly quiet, equivalent to petrol engine levels of smoothness and responsiveness. The Electronic Control Module uses a series of sensors to monitor injection pressure, timing, and volume, and signals adjustments in the fuel pump and fuel injectors to deliver the best performance.”
Here’s my take on it:
In the 1890’s Rudolf Diesel succeeded in selling his engine to a power-hungry industrial revolution, and although for decades it was employed mostly to drive heavy machinery, companies like Mercedes-Benz and Citroen had a serious attempt at refining it for everyday use in cars. Fortunately, the diesel engine has been continuously developed until the present today when many choose it ahead of the petrol engine.
Overall, the differences between diesel and petrol engines are not great, but the modern diesel engine is becoming increasingly popular for the following reasons:
* Typically, a diesel engine will go a third farther on a given amount of fuel than an equivalent petrol engine. You save money and, if being green is your thing, you’ll be happy that you’re using a third less fossil fuel (and you’ll be enthusiastic about the development of biodiesel).
* Diesel engines convert 40–45% of their fuel energy into heat energy, compared with the less efficient 25–30% of petrol engines.
* With proper use, diesel engines last longer than petrol engines because diesel fuel is a very effective lubricant. Petrol is a solvent and eats into engine oil, and that in turn promotes wear and tear throughout the engine’s moving parts.
* The diesel engine runs with an excess of oxygen (lean-burn) and therefore combusts fuel more completely than a petrol engine. So, modern diesel engines are cleaner overall than petrol engines: they emit less of three of the five problem gases.
* In the UK company car tax is linked to CO2 emissions; so if you have the RAV4 (190g/km) as your company car you’ll save yourself over £700 per year. Good news for Britian’s 1.7 million company drivers.
hehehe... aprub!... before.. it was the problem of diesels having slow acceleration and low top end speed... ngayon. iba na rin eh.... woohoo!!.. soon.. when i get enough money.. i'd still be buying a diesel!!...
May lumabas rin na VW diesel engine sedan that can go 0-62 mph in just 6 seconds at top speed nya is 150 mph. Hataw nga eh nung nireview ito sa top gear. DIESEL rules hehehehehehe!!!!
problema dito satin mejo madumi parin ang diesel eh...sana maumpisahan na ang pag linis nito..kahit anong ganda ng engine..kung pangit ang diesel natin...wala rin...
kaya pala gas lang lahat un euro brands dito. naisip ko din eh lagi ko napapanood sa top gear un mga diesel and all... pero ala dumadating dito. diesel dito mostly 2nd hand jap trucks. which is madumi din na talga and obsolete. pero atleast now siguro dahan dahan lilinis yan diesel coz of jap SUVS like pajero, patrol and lahat na diesel nauso now....
