Abstract
Official abstract text for this publication.
The invention relates to a method for starting and stopping an internal combustion engine of an industrial truck, wherein said industrial truck comprises an electric starter and an auxiliary hydraulic starter. Said method comprises steps of testing safety conditions (103), detecting instructions or requests from the operator (104), and testing auxiliary hydraulic starting conditions (105).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of starting and stopping an internal combustion engine of an industrial truck, said truck having an electric starter and an auxiliary hydraulic starter, the method of starting the internal combustion engine comprising the steps of: testing safety conditions, of detecting operator instructions or requests; and testing conditions for auxiliary hydraulic starting, wherein the auxiliary hydraulic starter is driven by discharge from a hydropneumatic accumulator, wherein the step of testing conditions for auxiliary hydraulic starting for the internal combustion engine includes testing the pressure of the hydropneumatic accumulator, wherein the step of testing conditions for auxiliary hydraulic starting for the internal combustion engine also includes testing that a time interval has elapsed since the last stop of the internal combustion engine, wherein the method includes starting the internal combustion engine as a function of the result of said testing steps and as a function of said detected operator instructions or request. 2. A method according to claim 1 , wherein the method of stopping the internal combustion engine includes a step of testing stopping conditions for the internal combustion engine. 3. A method according to claim 1 , wherein the step of detecting operator instructions or requests includes detecting action taken by the operator on a hand-operated or foot-operated control member of the industrial truck. 4. A method according to claim 1 , wherein the step of testing conditions for auxiliary hydraulic starting for the internal combustion engine includes testing the temperature of the internal combustion engine. 5. A method according to claim 2 , wherein the step of testing stopping conditions for the internal combustion engine includes a test that there is no activity and no request for operation of the industrial truck. 6. A method according to claim 2 , wherein the auxiliary hydraulic starter is driven by discharge from a hydropneumatic accumulator, wherein the step of testing stopping conditions for the internal combustion engine includes testing the pressure in the hydropneumatic accumulator. 7. A method according to claim 6 , wherein the step of testing stopping conditions for the internal combustion engine include testing the temperature of the internal combustion engine. 8. A method according to claim 6 , wherein the step of testing stopping conditions for the internal combustion engine includes testing an elapsed time interval since the last start of the internal combustion engine. 9. A method according to claim 6 , wherein the step of testing stopping conditions for the internal combustion engine includes a test of the state of the electric battery powering the electric starter.
