Compressed natural gas vehicle apparatus and method
View Patent ↗Systems and methods for installing a compressed natural gas housing apparatus to a vehicle are disclosed. The housing apparatus is configured to be retrofitted to existing cab liners used on refuse vehicles. The complete installation of the housing apparatus and roof liner are disposed below the roofline of the refuse vehicle. The housing apparatus can be configured to contain a variable number of compressed natural gas tanks. The housing apparatus is installed such that the length of the gas pipeline and electrical wiring connected to the apparatus from the vehicle engine and controller is minimized. The location of housing apparatus provides the additional safety of minimizing the exposure of the gas tanks to falling debris or prevent possible contact with the compressed natural gas tanks being damaged as vehicle travels under bridges, other low objects, or contact in the event of a rollover accident.
1. A method of installing a plurality of compressed natural gas (CNG) tanks on a vehicle comprising:
a. providing an apparatus including a frame to house the plurality of CNG tanks;
b. installing the plurality of CNG tanks in the interior of the apparatus;
c. installing the apparatus:
on the front face of a body of the vehicle,
below a roofline of the vehicle,
in a space between a cab and the body of the CNG powered vehicle,
and attached to a cab protector that prevents falling objects from damaging the cab;
d. connecting the CNG tanks to an engine of the vehicle; and
e. electrically connecting the CNG tanks to a controller of the vehicle.
2. The method according to claim 1 , wherein a substantial portion of the apparatus is located behind the cab of the vehicle.
3. The method according to claim 1 , wherein the cab protector apparatus is attached to the body of the vehicle.
4. The method according to claim 1 , wherein the plurality of CNG tanks comprises at least three tanks.
5. The method of claim 1 , further comprising transporting gas from the plurality of CNG tanks to the engine of the vehicle via at least one pipeline.
6. The method of claim 1 , further comprising providing an electrical connection between the plurality of CNG tanks and a control mechanism of the vehicle.
7. The method according to claim 5 , wherein the apparatus is installed such that it is located proximate the engine of the vehicle.
8. The method according to claim 6 , wherein the apparatus is installed such that it is located proximate the controller of the vehicle.
9. The method of claim 1 , further comprising using a manifold device to transfer natural gas from CNG tanks.
