The MTU 4000 series is a range of four-stroke industrial engines with rated outputs between 0.75 and 4.3 MW. In terms of design, they are diesel engines and the world's first series-produced engines with common rail injection . The 4000 series also includes gas engines; unlike diesel engines, they are equipped with a positive ignition system and are therefore gasoline engines despite their structural similarities.
The Series 4000 was presented at the SMM in October 1996. More than 37,000 motors of this type have been manufactured within 20 years. The series is a joint development by MTU Friedrichshafen and Detroit Diesel ; development started in 1992.
Type overview
The individual engines are named according to the following scheme: number of cylinders , engine type , engine series , area of application , two-digit number, application segment / design status , code letter for increased / reduced performance . So z. B. 16V 4000 R41L .
The areas of application are structured as follows:
- R : Engines for rail vehicles (diesel)
- M : engines for boats and ships (diesel)
- L : gas engines (Otto)
- G : generator motor (diesel)
construction
All engines are 90 ° V engines with either 8, 12, 16 or 20 cylinders; the cylinder bore is 170 mm, the piston stroke 190 mm or 210 mm depending on the series. The crankshaft rotates to the left. The fuel is injected with an electronically controlled common rail injection.
The engines have an air filter in each cylinder bank, which is directly connected to the turbocharger's compressor via a pipe bent by 90 °. The two turbochargers are located between the cylinder banks. The right-hand turbocharger, seen from the power output side, is switched on and off with electronically controlled hydraulic flaps as required. The compressed intake air is pushed out of the bottom of the compressor and fed through a pipe in the longitudinal direction of the engine to the water-cooled intercooler on the power output side of the engine. From there, the cooled intake air is directed downwards, in order to then reach the intake bridge via a 90 ° piece towards the control side (front) of the engine, which is located below the cylinder banks outside the V. The exhaust manifold is on the inside of the V and directs the exhaust gases into the turbocharger's turbine before they go up into the exhaust.
The water cooler and oil cooler, designed as plate heat exchangers, are installed on the front of the engine, alongside the coolant pump, switchable double fuel filter and either one or two oil centrifuges; two oil centrifuges require an automatic oil filter, which is available on request. The high pressure pump for the common rail system is installed under the oil filter.
The engine has individual cylinder heads, each with its own cylinder head cover. The two intake and two exhaust valves per cylinder are controlled by a camshaft below via tappets, push rods and rocker arms.
The engines can be started either with a 24V starter or with compressed air.
