BMW Diesel engines.

The small letter ‘d’ in the BMW model names stands for a difference with big results: every BMW diesel engine – whether four, six or eight-cylinder – delivers refined power and superb fuel efficiency.

The diesel engine transforms the chemical energy contained in diesel into mechanical energy. While petrol engines compress a mixture of air and fuel and ignite it with a sparkplug (externally-supplied ignition), diesel engines first compress pure air, which causes it to heat up. The fuel is later injected directly into the combustion chamber and ignites itself (self ignition). The direct injection with common rail technology enables the precise control of the ignition process, an even increase in pressure and the targeted burning of remaining soot particles by post injections. This minimises burning noises, makes running smoother and reduces emissions. 

The high compression ratio and pressure deliver generous torque even at low speeds and ensure efficient fuel combustion and thus lower consumption. Modern turbo technologies like the two-stage charging in the Variable Twin Turbo also increase the spontaneous power delivery and, in combination with modern automatic transmissions, minimise the response delay at low speeds. Thus BMW diesel engines combine the typical BMW dynamics and sportiness with smooth and refined running, low consumption and excellent acoustics.

The four-cylinder diesel in the BMW 3 Series Sedan 320d EfficientDynamics Edition, with 120 kW (163 hp) offers a powerful engine and a temptingly low average consumption of 4.1 litres of diesel per 100 km. The common rail injection technology ensures maximum running smoothness; and the BMW BluePerformance technology means BMW diesel engines already fulfil the EU6 emission norm that only come into effect in 2014. 

The BMW 740d Series six-cylinder diesel engine in the BMW 7 Series Sedan boasts an impressive 225 kW (306 hp) and a torque of 600 Nm. Thanks to innovative TwinPower Turbo technology the vehicle can be started at just above idling speed and has an electronically-controlled top speed of 250 km/h. The combination of both a large and a small turbocharger enable a powerful start and thrust even at high speed. 

Fuel consumption / CO2 emissions
Combined fuel consumption: 4.1 to 7.5 l/100 km
Combined CO2 emissions: 109 to 183 g/km

Brief Review on Truck Repair Services

Your truck must be considered as a machine instead of something that will allow you to haul cargo over long distances. As with all other machines, this machine must also be given appropriate care. If you fail to do so, you will be stranded someday in the highway. Repairing the truck at a truck repair center can turn out to be a highly expensive procedure. Why repair the truck when you can take precautions to avoid repairing it? Yes, that is what we will be looking into in the following passages. Given below are certain tips and strategies that must be kept in mind while driving the truck.

The next time you are driving, try to assimilate the sound generated by the truck. It might be noise to others, but you should not brush it aside so easily. This constant noise or hum is the only means by which your truck communicates about its condition. Here is an insider tip – always heed the noise levels generated by the truck. If it increases, then you must be doing something wrong. One of the primary symptoms that are being displayed prominently by these monsters is the alteration in the engine noise levels. The next time you think that the noise levels have increased, please take it to the nearest authorized service truck repair center. Let the experts look into it. Get all your doubts cleared by them. Replacing or repairing any parts of your truck is a costly affair. So, the economic way to own and utilize a truck is to study it inside out and avoid all possibilities that might lead to an untoward breakdown. The performance levels of your vehicle would certainly diminish over a certain number of years, but if it is served with regular maintenance and periodic checks, then certainly it would cover more miles before dying on you.

 The truck will be spending a major part of its life chugging along the road. If you wish to learn about the dirt levels present in our roads, please look at the underneath of the truck. If possible, try to wash it away with the help of pressurized water. The next time you cross a truck repair center, please take time to stop by and get the vehicle cleaned. Keeping the undersides clean will prevent rusting of the metallic components. Rust is the primary enemy of a machine. If viable, also invest on anti-rust coating for the truck’s body.

Overloading the vehicle with additional cargo might fatten your pockets. On the other hand, you are literally putting yourself and the truck at risk by doing so. Never exceed the threshold stated by the manufacturer. It is better to weigh the overall cargo before venturing out into the wilderness.

Every aging machine needs certain minimal degree of maintenance and repair jobs done on it. However, the quality of work done on the components of your truck determines the quality of its afterlife. So, before leaving your truck with a truck repair company make sure that they have the best mechanics available in the market.
