Letter Of Transmittal

Sir

I beg to transmit herewith for your inspection and approval the report which has been prepared by myself upon engine block heating system. That part of the report and bibliographic work upon engine block heating system entirely by me. This report has been unavoidably and materially delayed in its preparation, but this time has not been lost, since much of the foreign and other work on engine block heating system has been accomplished since it was begun.

Respectfully

Abstract

An engine block heating system for a vehicle and the associated method of its operation. The engine block heating system has an electrical heating element that is coupled to the vehicle's engine. A power cord is provided for supplying electricity to the electrical heating element from a source external to the vehicle. A sensor is provided for detecting whether or not the power cord is connected to the vehicle. A disruption switch is coupled to both the starting circuit of the vehicle and the sensor. The disruption switch disrupts the starting circuit of the vehicle when the sensor detects that the power cord is connected to the vehicle. As such, the vehicle cannot be started when the power cord of the engine block heating system is attached to the vehicle.

Block Heaters Diesel Engines

Introduction

Engine Block Heaters are used to heat the engine block and engine fluids of gas and diesel vehicles as an aid to starting in cold weather. The heater is operated using standard household AC power and the heat generated is distributed throughout the engine by the convective flow of the warmed coolant. Two basic types of heaters exist. The conventional heater is directly installed into the coolant jacket of the engine and the conduction heater is installed against the engine block or into a dry port of the engine.

Analysis

Typically they don't land on the desk of top decision-makers or lend themselves to innovative applications. Andy Rudderham, vice president of sales for Total Systems Ltd. in Mississauga, ON, says equipment dealers and gen set packagers are the only ones likely to get fired up about them. But whether you call them block heaters, water jacket heaters, or engine preheaters, they're essential to getting diesel-fueled gen sets up and running at full power in the 10 seconds that are standard for emergency power applications (Adair, 255-63). Block heaters don't get much attention because they're standard. Total Systems Ltd. is a dealer for Generac Power Systems—among other land and marine engine manufacturers—and services approximately 3,000 gen set installations nationwide, along with standby equipment it maintains in its own building (Anderson et al, pp 797-802).

Diesel Generator

Total Systems' emergency power is supplied by a Generac model SD080 diesel generator, 60 kW (347/600 V three-phase), which is in a Level 11 sound-attenuated enclosure and equipped with an 1,800 W, 120 V Kim Hotstart block heater, a double walled basetank for 36+ hours of ...
