CDX Chapter 13 Diesel Engine Cooling Systems

The flame temperature of diesel fuel is approximately

3900F

organic acid technology

A category of extended-life coolant containing carbon-based corrosion inhibitors,

hybrid organic acid technology

A combination of inorganic additive technology(IAT) and Organic acid technology(OAT) with nitrites added, making it suitable for use in both light and heavy-duty systems.

aeration

A condition in which excessive amounts of air or steam bubbles are dissolved in coolant, diminishing the coolant's effectiveness

inorganic additive technology

A diesel engine cooling system conditioner containing non-carbon-based corrosion inhibitors such as phosphates, borates, and silicate.

heat exchanger

A system that transfers heat from coolant to the atmosphere

coolant extender

An additive package that is only used with extended-life coolant

Supplemental Coolant Additive

An additive used to treat cooling systems to reduce the effects of cavitation erosion and optimize cooling system performance.

diesel coolant additive

An additive used to treat cooling systems to reduce the effects of cavitation erosion.

propylene glycol

An anti-freeze base that is non-toxic and environmentally friendly

Nitrated-organic acid technology

An extended-life coolant using organic acid technology(OTA)

DCA

Diesel coolant additive

cavitation

Erosion in cylinder block walls, heads, and liner sleeves as a result of the collapse of tiny water vapor bubbles formed when coolant vaporizes on hot cylinder wall surfaces.

ELC

Extended-life coolant

HOAT

Hybrid organic acid technology

NOAT

Nitrated-Organic Acid Technology

OAT

Organic acid technology

extended-life coolant

Several types of ling-life coolant formulations containing an anti-corrosion additive package that does not deplete; also known as long life coolant.

SCA

Supplemental Coolant Additive

Thermal Efficiency

The ability of an engine to convert the energy content of fuel into mechanical force.

ethylene glycol

The base chemical from which the majority of ant-freezes are made.

electrolyte

The base chemical from which the majority of anti-freezes are made.

heat rejection

The transfer of heat into the cooling system from the combustion chamber.

The release of heat to the cooling system is called ________ ______________

heat rejection

IAT
