ENVIRONMENTAL DIAGNOSTICS OF DIESEL FIRE TRUCKS BY A ROBOT-MANIPULATOR IN DYNAMIC LOADING MODE

This article presents a critical analysis of the development of an approach for inplace diagnostics of fire engine fuel systems and engines using an electronically controlled robotic manipulator under operating conditions. The authors' theoretical concept of this approach is based on empirical relationships between the time interval of a diesel engine's «acceleration» in free acceleration mode, the angular velocities of the crankshaft and the conventional «reference» value of its acceleration in the standardized mode of full fuel delivery. A further development of the theory of a new approach in the field of environmental safety is considered in the mathematical expression of the «instantaneous» inertial load as a function that, in an original way, sums up the argument functions of the main components of the dynamic «resistance» in the control system mode. Calculating these components is the engineering output of a scientific approach that allows for the reliable calculation of «technical environmental safety standards» Applying this approach to research on a D-240L diesel engine resulted in a drag moment value. Statistical studies on 82 PAs established the significance of the smoke emission dependence on mileage, confirming the standard smoke emission range for serviceable Fire Trucks and the expected value of prevented damage from excess fuel consumption of up to 64.6 tons per year.
