Abstract

A system and method of operation for golf cars or the like employing electrically operated fuel injected engines for that can be operated in substantially the same manner as electrically powered cars to effect rapid restarting of the engine after stopped and with the main switch left on without excessively depleting the battery power.

Claims (22)

1. A golf car comprising:

a body portion supported on a plurality of wheels and including a passengers' compartment arranged to accommodate at least an operator,

at least one of said plurality of wheels mounted to said body portion and arranged to be steered by the operator,

a fuel injected, internal combustion engine mounted to said body portion and arranged to drive at least one of said plurality of wheels through a transmission,

an electrically operated fuel injector arranged to deliver fuel to said engine,

an operator controlled accelerator arranged to electrically operate said electrically operated fuel injector and to control the operation of said engine between a non running condition and a running condition,

a main switch arranged to control supply of electrical power to said electrically operated fuel injector, the main switch being arranged to move between an “off” condition and an “on” condition, and

a holding circuit arranged to supply electrical power to said electrically operated fuel injector in response to operator demands until a predetermined condition exists after which the electrical power supplied to the electrically operated fuel injector is stopped even when the main switch is in the “on” condition.

2. A golf car as set forth in claim 1 , wherein the predetermined condition is a time period.

3. A golf car as set forth in claim 1 , wherein the holding circuit is switched to an “off” condition if the main switch is switched to the “off” condition during the predetermined condition.

4. A golf car as set forth in claim 3 , wherein the predetermined condition is a time period.

5. A method of operating a golf car comprising:

providing a body portion supported on a plurality of wheels and including a passengers' compartment arranged to accommodate at least an operator,

providing at least one of the plurality of wheels mounted to the body portion so as to be arranged to be steered by the operator,

providing a fuel injected, internal combustion engine mounted to the body portion and arranged to drive at least one of the plurality of wheels through a transmission,

providing an electrically operated fuel injector arranged to deliver fuel to the engine,

providing an operator controlled accelerator arranged to operate the electrically operated fuel injector and to control the operation of the engine between a non running condition and a running condition,

providing a main switch arranged to control supply of electrical power to the electrically operated fuel injector, the main switch being arranged to move between an “off” condition and an “on” condition and

a step of supplying electrical power to the electrically operated fuel injector in response to operator demands until a predetermined condition exists after which the electrical power supplied to the electrically operated fuel injector is stopped even when the main switch is in the “on” condition.

6. A method of operating a golf car as set forth in claim 5 , wherein the predetermined condition is a time period.

7. A golf car as set forth in claim 5 , wherein the holding circuit is switched to an “off” condition if the main switch is switched to the “off” condition during the predetermined condition.

8. A golf car as set forth in claim 7 , wherein the predetermined condition is a time period.
