0000007350 00000 n From installation scheme we can see that the measuring chambers are installed after the fuel fine filter, and through them a large flow of fuel is passing. This density change on its own could easily result in a 1% change in volume if the return diesel is around 25C higher in temperature than the supply from the fuel tank. The first involves a complete fuel system re-build and therefore is not usually practical.

Resume:No any reasons to be afraid of Eurosens Delta fuel meters.No any engine or fuel meter problems during everyday operation. As an illustration of the calculation of Blended Rate for a Taxable Year, if the Corporate Taxpayer solely files Tax Returns in State 1 and State 2 in a Taxable Year, the maximum applicable corporate tax rates in effect in such states in such Taxable Year are 6% and 5%, respectively and the apportionment factors for such states in such Taxable Year are 60% and 40%, respectively, then the Blended Rate for such Taxable Year is equal to 5.6% (i.e., 6% times 60% plus 5% times 40%). The prime intention of this work is to provide a maximum replacement for diesel using hydrogen in a common rail direct injection equipped diesel engine. hydrogen crdi higher My D4 EVC equipped boat has a fuel consumption read out on the tachometer, along with other readings. In the combustion chamber, diesel fuel was injected at a crank angle of 23 bTDC, making it an ignitor for the premixed mixture of hydrogen and air. Performance, emission and combustion studies were made with the different levels of hydrogen injection, which proves that the 30LPM of hydrogen provide the best results. Meter can see only one reed switch pulse per chamber rotation, so cant detect its direction. But according to this scheme you need to install 2 non-return valves (check valves) in each chamber of fuel meter. 0000003454 00000 n When it worked it was brilliant but the volumetric senders were delicate, became bunged up with the slightest thing, were position and vibration sensitive and the whole system would occasionally just not work for no apparent reason. All is not totally lost in this diesel flow measurement application as an acceptable metering system can be achieved in one of 2 ways. Fluid flow measurement is always difficult, especially relatively low rates of flow, requiring accurate measurement. The electronic control unit helps to induct the hydrogen for a period of 211 CA during the suction stroke. If bypass valve of engine opens at 1 Bar (sometimes even at 0.5 Bar), with check valves fuel pressure in supply channel is growing. Only fuel consumption flow rate must pass via single-chamber flow meter, without return flow. Eurosens Direct PN100 -10000 mm3. These valves usually open with pressure 0.25 Bar approx.On big fuel flows these valves also add its hydraulic resistance. Great care has to taken to ensure that the fuel temperature does not rise excessively hence a return flow intercooler is required as is a substantial tank volume to ensure that there is no foaming and the fuel is not too hot for the engine fuel system as this will reduce horsepower. With this innovation we can detect direction of fuel flow and no need in check valves.So, you can install only Eurosens Delta flow meter that have no any affect to fuel supply system.

The single flowmeter is only measuring the fuel supplied to the secondary tank and has therefore has to have the ability to meter the consumption over the whole range of the engine. The condition of the engine is also critical as indicated previously if it is not in first class running order the return line could contain spurious amounts of gas increasing the apparent volume of the return flow.

Fuel tank is heating with less, because return fuel flow after fine fuel filter is cooler compared to return fuel flow from high pressure fuel pump (before modification). 0000007504 00000 n However this would not be true for a refrigerated lorry delivering produce in a city where a large proportion of the duty cycle is at low power and hence measurement of flow in this situation would be prone to greater errors. I appreciate that petrol flow is much easier to measure. The diesel one was a pain in the ars. 0000111304 00000 n If you wish to measure the amount of fuel used you simply need to place one fuel flow meter in the supply line and a second in the return line and use electronics to subtract the difference.
