Due to recent fuel efficiency issues and changes in the automotive environment, Europe and Japan are considering introducing new testing regulations called RDE (Real Driving Emissions), which involve random and dynamic real-world driving. Furthermore, in vehicle development, there is a growing demand for "instantaneous" fuel efficiency measurement during driving, rather than just transient measurements.
The FP-4135 / DF-2200 is primarily targeted at returnless engines, which have become mainstream in gasoline vehicles. It combines compactness that allows it to be mounted in the engine compartment with high functionality, enabling fuel consumption measurement for all types of internal combustion engines.
The FP-4135 vehicle-mounted flow detector offers a wide flow rate range of 0.1 to 200 L/h, enabling measurements from idling to high-load conditions in small to large passenger vehicles. It also supports a wide range of ambient temperatures, from low to high, and alcohol fuels, enabling fuel consumption measurement in various environments, from on-board measurements to chassis dynamometer measurements.
Features
FP-4135 Vehicle-mounted flow detector
Wide range, high precision
Flow measurement range 0.1 to 200 L/h, accuracy ±0.2 %, resolution 0.01 mL
