A, product introduction
FYYH type automobile fuel consumption measurement instrument is dynamic test and display the instantaneous fuel consumption cars, cumulative oil consumption measuring instrument, the fuel consumption instrument host and CPU display two parts,
For public transport vehicles, passenger vehicle, freight vehicle and engineering vehicles and so on accurate fuel consumption statistics and oil quota management, for the pilot to improve oil saving operation skill, for countries to increase energy saving
Emission reduction strategy, and provides an effective fuel consumption test method, which can be emissions have according to the.
Working principle
1, into the fuel consumption instrument host within the fuel quantity through the precise flow sensor, and to the form of electrical signals transmission to the CPU, the CPU calculation analysis and display fuel consumption and other related data.
2, into the fuel consumption instrument host fuel through the fuel consumption instrument flowline into the oil pump, and through the high pressure oil pump oil inlet to the engine oil.
3, engine oil return through the high pressure oil pump return line into the fuel consumption instrument host, and through the fuel consumption instrument host internal circulation to enter the fuel consumption instrument pipeline and oil transfer pump.
4, built-in automatic exhaust system used to set up the operation or changed after oil, discharge fuel consumption instrument air in the host.
5, through the fuel consumption instrument host internal circulation to the engine oil, fuel temperature is higher, there are certain oil-saving effect.
