An active DTC limits the maximum engine torque to approximately 40% after the engine has been running for 50 hours. Check for leaks in the air supply system or intake manifold. With a new design of the combustion chamber, injectors and cooling system we can cut fuel consumption with up to 0.7%. Check the wiring pin connections to the control unit and the braid wiring in the cylinder head. Short circuit of the solenoid valve bypassing the turbine to ground. Check the opening pressure of both relief valves. The crankshaft sensor registers the rotation of the engine, but the camshaft sensor does not generate pulses. Over the years i always got better fuel in Scanias than the equivalent Volvo but a more marked difference still when the Scani is driven manually, but found the Volvo's to be a tougher more durable vehicle overall, swings and roundabouts. Truck specifications. The sensor is connected to the wrong pin in the engine control unit connector. The minor difference in fuel consumption between the two will pale into insignificance when something goes wrong with either. Zużycie paliwa ciągnika siodłowego Scania R420 Topline z 2004 roku, ... Fuel consumption of the 2004 Scania R420 Topline with loaded semitrailer. The pressure sensor in the fuel line, the coolant temperature sensor, the charge air pressure sensor, the charge air temperature sensor and the fan speed sensor have a common power supply. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors. I had a new R440 new in 2010 and drove it for two years. CNG combustion produces fewer undesirable gases than the aforementioned fuels. Torque. Improved technology. Newtonmore Grill Truckstop. In the event of a fault in one of the sensors, it may affect the electrical circuits of the other sensors. Notify the driver about the possibility of engine damage when the engine is running at high speeds. Victorious four years in a row. The control unit must perform the test in four consecutive cycles. A fault code will be recorded only if the pressure in the fuel line exceeds the set value for 7 seconds or a longer time interval. The fault code cannot be cleared while the fault is present. Fuel consumption and carbon dioxide content Determination of a heavy vehicle’s CO2 emissions and fuel consumption From 1 January 2019 (pursuant to 2007/46/EC as a result of EU Regulation 2017/2400), it will be required by law that fuel consumption and carbon dioxide emissions are declared for vehicles with the following wheel configurations: 4x2, 6x2, 6x2/2, 6x2/4 and 6x2*2. Fuel pressure in the pressure accumulator. Price N$ 850,000. The fuel pressure in the ramp drops even in spite of the fact that the fuel metering inlet valve is completely closed and the fuel is not consumed. Petrol tank. During the training we focus on how to cut fuel consumption and minimise repair … If a malfunction code is generated when the engine is running by inertia (for example, when the vehicle is going to descend with the accelerator pedal fully released), to facilitate troubleshooting, you can use the “Stored operational data” option on the “Pressure” tab supply “(” Supply Pressure “). The engine stops or goes into emergency mode. The system continues to attempt to use nozzles. An active DTC cannot be deleted from the control unit. Short circuit of the solenoid valve bypassing the turbine on the + battery. The tall diff ratio, did mean that cruising revs were relatively low, and that, according to Alan, is where it needs to be to get the optimum fuel economy. The voltage in the circuit was below acceptable levels. Troubleshoot by comparing the charge-air temperature sensor with the atmospheric pressure sensor and the backpressure sensor in the exhaust system. The voltage in the electrical circuit was above normal. Put it this way I drive the same way and my FH16 750 leaves the R440 behind for fuel consumption.
