1.44.5. Purchase of the second-hand engine

Be attentive at purchase of a second-hand diesel engine Diesel engines work long, but it does not mean, that you should not examine all traditionally worn out places. On some engines it is very easy to disguise both duration of operation, and deterioration. At an estimation of a condition of such engine there is a danger "лопухнуться" if you badly understand diesel engines.

As well as at petrol engines, the diesel engine exhaust should be the homeless. Besides, there should not be a smoke an open mouth маслоналивной tubes on прогретом the engine. As to a diesel engine it is peculiar big шумность, than to the petrol engine, you should distinguish working noise from knock of the worn out pistons, rods, a cam-shaft and тд. If at you doubt concerning an engine condition address for the help to professionals.

Turbodiesels are very popular, as the turbo-supercharging is well entered in diesel engine characteristics. Турбокомпрессоры work with small pressure of pressurisation and on small turns of the engine that provides with it longer, than for petrol engines service life. Turbodiesels excellently approach for tractors and multiton lorries.

However it is difficult to diesel automatic devices to correspond to inquiries of an automatic transmission because of the flat characteristic of the twisting moment. Only few manufacturers are disturbed by this problem. Among them Citroen, Mercedes, Peugeot and recently joined them Opel, but also that they apply automatic transmissions only by middle class cars.

Thanking all accruing popularity, on diesel engines do not look any more as at the poor relative, and on level of the furnish they completely correspond to the petrol colleagues

At purchase pay attention to residual cost of a diesel engine. In due time diesel cars have given a push to growth of a sales volume of cars in Germany, but the sales volume peak has been reached still four years ago and till now there is a gradual recession so be convinced, that you do not overpay for honour to become the owner diesel авто.

Check up run. Diesel cars are bought up for their potentially high reliability and probably big run Especially when they are bought by the new. But it at all does not mean, that you should not pay attention to the run counter. Really, many dealers do not like to deal with the cars which run has passed for 80 thousand in km and, accordingly, adjust the price for them. Or, not philosophising crafty, simply dump run on the counter Run in 160 thousand in km it is quite natural to well served diesel engine, but think twice if the counter shows 320 thousand in km or, especially, if this second-hand taxi with such run.

Except for the engine, the majority of diesel cars on the device are identical to the petrol colleagues, the same concerns and suspension brackets, brakes, but consider the prices for spare parts. For example, exhaust systems serve long, but differ from similar petrol engines. And if you have got used to buy spare parts at разборщиков emergency cars keep in mind, that details of petrol engines can be outwardly similar and approach in the sizes, however the block of cylinders of a diesel engine differs from the similar block of the petrol engine and in most cases cannot be chosen as replacement. Transfer numbers of transmissions and coupling also differ.
