They’ve decided that they know better than you how you want the car to function. The TM6 is an advanced electronic control system that will shut engines down in an emergency situation. The Series 300 and 310 systems will only give auto- matic shut down on engine overspeed, operation of the emergency stop button or, where fitted, sensor trip or break in the sensor circuit. You know the drill: choke at three-quarters (not eleven sixteenths or seven eighths), two pumps on the gas, count ‘one potato, two potato’, pray, start - like that, hopefully. NASA will hold a press conference in about 2 hours (about 7:30 p.m. EST or so). During the next execution of the restart control routine, the program proceeds from the decision point 356 to a decision point 364 where the condition of the spring release solenoid is determined. Enable time delay changes automatically with engine temperature. A normally open door switch 138 has one side coupled to the positive terminal of the vehicle battery 133 and the other side coupled to one input of the input discrete section of the input/output circuit 110.

From step 232, the program proceeds to 228 where the spark disable flag is reset to indicate that normal spark is to be provided to insure combustion of all of the fuel-air mixture entering the combustion chambers during the shutdown period. The automatic shutdown of propulsion machinery is only required when the fixed gas fire extinguishing system is activated and when the machinery draws its intake air from within the protected space. Referring to FIG. But what this means for you, the car owner is: you have to wear it. If the spark disable flag is reset indicating desired normal spark, the program proceeds to the step 414 where the spark timing and dwell values determined during the spark control routine 162 of FIG. The real reason these automated systems exist in many new cars is so that the carmaker can legally ‘game’ the official fuel consumption tests. If it is determined that the vehicle gear selector is in L1 or L2, the program proceeds to a step 204 where an emergency restart flag is set to force an engine restart as will be described. If, however, both of the windings 315 and 330 are energized, the chamber of the forward drive clutch is rapidly filled by the pressurized fluid in the accumulator 318 due to the unrestricted fluid coupling through the valve 328 in parallel with the restricted fluid coupling through the orifice 332 and the valve 314 to provide a rapid increase in the engagement force of the forward drive clutch. This ES series engine shutdown system is available for shutting down up to eight circuits with engine circuit relays featuring an operating range of 100mA to 10 amps. It’s basically a ticking time bomb like that - or, more accurately, it’s pretty easy to kick over - it doesn’t really take much of a nudge from the starter to get the whole thing turning and burning in that state. If the vehicle speed is greater than the reference speed SPD3, the program proceeds from point 262 to the decision point 266 where the condition of the emergency restart flag is sampled. © 2004-2021 FreePatentsOnline.com. However, if the vehicle is at rest, the program proceeds to the decision point 224 where the state of the manual shutdown switch 139 is sampled. And sure, you can press and hold the button to temporarily disable it, but every time you get back in the car for a fresh crack at driving, it’s default state on startup is ‘active’.
