 CONTROLLING COMBUSTION ENGINES (vehicle fittings for automatically controlling vehicle speed B 60 K 31/00; cyclically operating valves for combustion engines F 01 L; controlling combustion engine lubrication F 01 M; cooling internal-combustion engines F 01 P; supplying combustion engines with combustible mixtures or constituents thereof, e.g. carburettors, injection pumps, F 02 M; starting of combustion engines F 02 N; controlling of ignition F 02 P; controlling gas-turbine plants, jet-propulsion plants, or combustion-product engine plants, see the relevant subclasses for these plants) [4]
 

Notes

(1)

 In this subclass, the following term or expression is used with the meanings indicated:
 

-

 "fuel injection" means the introduction of a combustible substance into a space, e.g. cylinder, by means of a pressure source, e.g. a pump, continuously or cyclically acting behind the substance;
 

-

 "supercharging" means supplying to the working space, e.g. cylinder, combustion-air pressurised by means of a pressure source, e.g. a pump.

(2)

 Attention is drawn to the Notes preceding class F 01.

(3)

 In this subclass, electrical aspects of control arrangements are classified in groups F 02 D 41/00 to F 02 D 45/00. [4]

 

 

 

Controlling, e.g. regulating, fuel injection (peculiar to engines characterised by their use of non-liquid fuels, pluralities of fuels, or non-fuel substances added to the combustible mixtures F 02 D 19/00; peculiar to supercharged engines F 02 D 23/00; automatic controllers for prime movers, in general G 05 D)

/ 00 Controlling fuel-injection pumps, e.g. of high-pressure injection type (F 02 D 3/00 takes precedence) [2]

1
/ 02 • not restricted to adjustment of injection timing, e.g. varying amount of fuel delivered  

1
/ 04 • • by mechanical means dependent on engine speed, e.g. using centrifugal governors (F 02 D 1/08 takes precedence)  

1
/ 06 • • by means dependent on pressure of engine working fluid (F 02 D 1/08 takes precedence)

1
/ 18 • • with non-mechanical means for transmitting control impulse; with amplification of control impulse  
 

 3
/ 00 Controlling low-pressure fuel injection, i.e. where the air-fuel mixture containing fuel thus injected will be substantially compressed by the compression stroke of the engine, by means other than controlling only an injection pump (carburettors F 02 M) [2]

Note
 

When the control apparatus or system forms part of the low-pressure fuel-injection apparatus it is classified in group F 02 M 69/00. [5]
