The new Mercedes-Benz OM 470 - The six-cylinder in-line OM 470 engine with a variation of 10.7 l is the most compact of the sturdy engines from Mercedes-Benz. It is the engine of selection when compact building and construction, reduced weight, high efficiency, great drawing power, optimum efficiency, low gas consumption as well as lengthy upkeep periods are needed.
The new Mercedes-Benz OM 470
The new top-of-the-range variant has a power result of 335 kW (456 hp) as well as powerful torque of 2200 Nm. The OM 470 is readily available in five variations from 240 kW (326 hp), ideal for heavy short-radius distribution, long-distance haulage and building traffic.
Fuel injection, exhaust gas recirculation and turbocharger revised
Fuel shot remains to be based on the X-Pulse shot system with typical rail and also stress increasing in the injector. Nevertheless, the maximum rail stress has actually been elevated from 900 bar to 1160 bar. This causes a shot pressure of up to 2700 bar. There is likewise a new shot nozzle, a reshaped burning chamber and greater compression. The steep boost in torque as well as efficiency indicates a lower rated speed of just 1600 rpm as well as a more responsive engine.
Improved exhaust gas recirculation (EGR) monitoring minimizes the EGR price and reduces gas consumption. An uneven shot optimises tire gas high quality. Also brand-new is the supremely effective turbocharger produced inhouse. The pilot-actuated procedure means that the wastegate shutoff, the boost stress control, EGR sensing unit and also EGR control are no more required, reducing intricacy and increasing effectiveness.
The trucks additionally take advantage of fuel-efficient engine oils, redeveloped gear boxes and a refined driving approach from the Predictive Powertrain Control (PPC) cruise ship control.
As a result of the various measures embarked on, the cost savings vary for each engine-- yet they are certainly visible for all engine versions. The changes to the engine and drivetrain imply fuel intake is decreased by as much as five percent in an Actros with the OM 470 engine. The result of the present enhancements in addition to previous modifications to the engine leads to a reduction of approximately six percent in an Actros with the OM 471 engine. The huge OM 473 with 15.6 l displacement take advantage of redeveloped fuel injection with as much as three percent reduced fuel consumption.
Engines approved for alternative fuels
Hydrotreated Vegetable Oil (HVO), Biomass to Liquid (BtL), Gas to Fluid (GtL) as well as Coal to Fluid (CtL) are different fuels according to the prEN 15940 standard, made from a series of sources which are transformed to gases through chemical procedures. Mercedes-Benz Trucks has actually accepted them for usage in the most up to date OM 470 and OM 471 engines. The compatibility of these fuels has been confirmed in thorough tests and also the engines are designed for them as requirement.
All fuel sub-groups of the prEN 15940 standard are essentially comparable to gasoline made from mineral oil, so no changes whatsoever are required to the engines or their peripherals. The injection procedure, fuel lines as well as seals remain unmodified. The very same is likewise real of the periods for oil changes as well as for cleansing the particle filter, as well as the service warranty and warranty continue to apply without constraints. The result and torque information remain the exact same.
