Precise Testing at Full Throttle Test station for pumps with linear wear for fuel preparation in consumption and emission measurements
In 2.5 seconds from idle mode to maximum rotation speed – the engine whines …
A consumption measurement is no walk in the park for engines and testers: In the simulation of maximum acceleration, the engine is accelerated under full load from an idle mode to maximum rotation speed in less then three seconds. While doing so, the tester recognizes if the fuel volume ideally suits the air volume – if not, the software engineer must adjust the engine control which consists of approximately 200,000 program lines.
It goes without saying that these tests must be absolutely accurate: In order to be able to optimally calibrate and adapt the engine parameters, a modern test station with ideal fuel preparation by means of SCHERZINGER pumps is required.
With SCHERZINGER, we can finally plan maintenance intervals accurately because the wear of the pump is precisely predictable.
Fastidious High-Tech Pumps – accurate to the microleter
The efficiency of modern combustion engines – specifically for road vehicles – is becoming increasingly important and is thus monitored by legislators.
How much gas does an automobile need according to the WLTP and what emissions does it emit? These parameters are analyzed in the consumption measurement: In automotive production, as in series production as well, the fuel consumption and the emissions of the engines must be measured accurately and optimized. The test stations designed specifically for this purpose have calibrated testing devices which measure the fuel, oil, air and urea (DEF).
The fuel supply unit is connected before the test object and conditions the fuel exactly to the desired operating point (pressure and temperature). The consumption quantity is precisely recorded, down to a few microliters – even in a highly dynamic, mobile operation.
Maximum measurement precision in a very wide operating range
from the idle mode of a small car to the full throttle of high-performance vehicles on the freeway
High test station availability with schedulable maintenance intervals
High measurement dynamics for the dynamic drive mode
Constant flow with minimal pulsation
gear pump technology
High corrosion resistance
universally applicable for the most diverse fuels – even racing fuel
The base pump as a versatile specialist
SCHERZINGER has developed this pump specifically for this use and, to that end, placed a lot of value on covering an extremely broad application spectrum with one base pump. You profit from this as follows:
- Rapid attainment of engine and vehicle development objectives
- Reduction of the measuring effort in the automatic engine calibration
- Higher economic efficiency of the engine test field (due to low product lifespan costs and quality service)
- Long lifespan and linear wear behavior for simple planning of maintenance
