Engine output condition informing system for snow remover
First Claim
1. A system for informing output condition of an internal combustion engine mounted on a snow remover having a snow removal mechanism and a travel mechanism such that at least one of the snow removal mechanism and travel mechanism is driven by the engine in response to an instruction of an operator, comprising:
- an engine speed sensor detecting speed of the engine;
a throttle position sensor detecting position of a throttle valve of the engine;
an engine output power rate estimator estimating an engine output power rate based on the detected speed of the engine and position of the throttle valve;
an engine output condition determiner determining output condition of the engine based on the estimated engine output power rate; and
an informing device informing the determined output condition of the engine to the operator.

Abstract
In an engine output condition informing system for a snow remover, the engine speed and the throttle position are detected, the output power rate OPrate of the engine is estimated based thereon, the output power condition of the engine is determined based on the estimated output power rate, and the operator is informed of the determined output power condition by the display (informing) device. With this, the output power condition of the engine can be accurately determined and the operator informed with a simple configuration, whereby the burden on the operator can be lightened. Also, it is possible to minimize situations in which the output power condition of the engine is overpowered and the power train of the engine or of the snow removal mechanism and travel mechanism is damaged, as well as situations in which the output power condition of the engine becomes underpowered, the snow remover is unable to perform, and the operating efficiency decreases.
