Abstract

A transport refrigeration system (200) including: a first engine (26) configured to power a refrigeration unit (22); a first fuel tank (330) fluidly connected to the first engine (26) through a firstfuel line (332); a first shut off valve (450) located within the first fuel line (332) proximate the first fuel tank (330); a second shut off valve (72) located within the first fuel line (332) proximate the first engine (26); a sensor system (80) configured to detect at least one of a crash of the transport refrigeration system (200), a crash of the first fuel tank (330), a fuel leak in the firstfuel line (332), and an engine stall in the first engine (26); and a controller (30) configured to close the first shutoff valve (450) and second shutoff valve (72) when at least one of a crash of the transport refrigeration system (200), a crash of the first fuel tank (330), a fuel leak in the first fuel line (332), and an engine stall in first engine (26) is detected.

Description

technical field

[0001] The subject matter disclosed herein relates generally to transport refrigeration systems, and more particularly, to fuel systems for such transport refrigeration systems. Background technique

[0002] Generally, cold chain distribution systems are used to transport and distribute goods that may be susceptible to temperature, humidity, and other environmental factors, or more specifically, perishable items and environmentally sensitive items (referred to as perishable items in this paper) . Perishable items may include, but are not limited to, fruits, vegetables, grains, beans, nuts, eggs, dairy products, seeds, flowers, meat, poultry, fish, ice, and pharmaceuticals. Advantageously, the cold chain distribution system allows perishable items to be efficiently transported and distributed without damage or other undesired effects.

[0003] Refrigerated vehicles and trailers are commonly used to transport perishable items in cold chain distribution system...
