This standard specifies the direction of action of the hand-operated control mechanism for speed regulation and reversing of reciprocating internal combustion engines, especially for marine and railway traction reciprocating internal combustion engines, regardless of whether the operator is close to or far from the engine. Control valves for liquids and gases are not included.

GH/1' 4672—2003/[S0 2261.1994 Manual control mechanisms for reciprocating internal combustion engines
Standard direction of movement
This standard specifies the operator position in the direction of movement of manual adjustment and reversing control mechanisms in reciprocating internal combustion engines: in particular for registered and non-regulatory use, including parking close to or away from the engine, excluding gas control and fire control. 2 Effect of the control mechanism
2,1 When the reversing and speed control mechanisms are separately set, the control mechanism can reduce the speed of the longitudinal speed control mechanism in the reverse direction: 2.2 When the reversing and speed control mechanisms are combined, the longitudinal control mechanism and the longitudinal speed control mechanism can accelerate the forward and backward travel. The longitudinal control mechanism moves from the central position to the opposite direction to accelerate the rear travel. The control mechanism moves from the central position to the central position to decelerate the travel. The control mechanism moves from the central position to the full position to the full position to decelerate the travel. The control method is shown in Table 1 and Table 14. The best position of the operator on the equipment is for the operator to see the direction of travel of the vehicle. The best position is set to face the front of the vehicle. If the position of the operator is set to be parallel to the direction of travel of the vehicle (looking vertically and sideways), the operator's position should be set or the control direction of the control material should be in accordance with the standard text 5 markings of this department. In order to clarify the effect of the control rate, standard symbols should be set next to the control mechanism, and the symbols are text (as shown in Table 1). These symbols include 1S07000 and JE: 17. Table 1 Exploration direction and effect selection markings when the reversing and speed regulation control mechanisms are set separately
