Patent DE-3931308-A1 (DE)
Title: Controlling temp. of heated measuring resistor - taking into account change in working temp. during evaluation of measuring voltage
Inventor: STIEFEL HANS-PETER
IPC: G01F1/68
Filed: 1989-09-20
Abstract: The measuring resistor is pref. a heated resistance wire or similar of an air flow measurer of an IC engine which, during measuring, esp. as air streams by, has a working temp. higher than the temp. of the air stream. This working temp. can assume various values in dependence on a reference value. A change in this working temp. is taken into account during evaluation of the measurement results, i.e. the measuring voltage (U). The working temp. can be varied in steps or continuously. The reference value can be derived from measurement values. The reference value can be the r.p.m. of the IC engine and/or the angle of the throttle flap and/or the measuring voltage (U) itself. The working temp. is set according to a desired measuring range. ADVANTAGE - High resolution of measurement result even at low air intake level, esp. while idling or partial loading.

Title: Diesel engine fuel injection valve - delays pressure rise and fall in back pressure chamber to allow valve operation
Inventor: TSUZUKI NAOYUKI
IPC: F02M47/00
Filed: 1990-12-27
Abstract: The fuel-injection valve has a nozzle body (18) with a seat (28), against which a needle valve (26) is spring-loaded (46). A fuel pressure chamber (32) is pressurised to lift the needle off its seat, while at the valve end away from the seat is a backpressure chamber (42), in which fuel pressure thrusts the needle against the seat. A passage (54,56), connecting the backpressure chamber to the fuel pressure source (10), contains a flow regulator. As pressure from the source rises, it delays pressure rise in the backpressure chamber as compared to that in the pressure chamber, allowing the needle valve to open. As the source pressure falls, it delays pressure reduction in the backpressure chamber as compared to that in pressure chamber, allowing the valve to shut. ADVANTAGE - Rapid injection cut-off, while preventing reverse flow of combustion gases into injector.
