The main topic of the article is the development of an effective design for a pre-starting heating system for an internal combustion engine for conditions of limited power supply. The work to im-prove the design of light wheeled all-terrain vehicles on low pressure pneumatics is done at Pacific National University. Prototypes of light wheeled off-road vehicles are used mainly in agriculture and for forestry production. There are prerequisites for their use in oil and gas fields in the Far North conditions. This vehicle is operated all year round, in the absence of power supply, it is stored in the open air, so the problem of starting a cold engine is quite important, and the topic of creating a design for a pre-starting heating system for an internal combustion engine under conditions of limited or com-plete absence of power supply is relevant. The purpose of the work is to develop and study the efficiency of the pre-starting heating system for an internal combustion engine with liquid cooling for conditions of limited power supply. Our own design of the cooling system with a pre-starting heating function based on a gasoline burner was developed. To assess the efficiency of the engine warm-up process, the circuit was as-sembled on a light wheeled all-terrain vehicle. The experimental studies were carried out to deter-mine the regularity of changes in the temperature of the engine coolant during pre-starting heating at different ambient temperatures. The results of the experiment indicate the high efficiency of the developed system based on a gasoline burner. The average heating rate of the engine coolant during the warm-up process was 2.1 - 2.8 оС per minute, which indicates an intensive pace of pre-starting heating.

And Control

The internal combustion engine that equips a vehicle is a complex assembly of mechanical parts and electronics that controls almost every system. The electronic part of the vehicle gives the opportunity to observe and control what happens with the engine during function. The present paper follows the evolution of the pollutant emissions in relation with some transitory regimes of the car.

Step Responses

A procedure based on measured step responses, is presented for the pseudo-decoupling of basically linear, nonoscillatory, multivariable plant. The method generates pre- and post-compensator matrices that will tend to make an otherwise nondominant plant diagonally dominant. Once this is achieved, each loop is then tuned on an individual basis using one of the classical on-line methods, thus eliminating the need for a model. The method is illustrated by means of two examples. The first demonstrates the design procedure and the second reports on the application of the method in controlling the power generated by an internal combustion engine.

This paper presents the structure and operation of an integrated data acquisition and control system for analysis of the performance characteristics of an internal combustion engine in a testbed. The system allows on-line monitoring of different engine parameters and also enables us to obtain automatically the operating curves of the engine and to compare them with those provided by the manufacturer in order to assess the condition of the engine. With this system, engineering and graduate students are able to monitor the engine continuously and to check the effect of different working conditions on its performance.

The Moment

A natural gas-fired micro-cogenerator (MCHP) based on a reciprocating internal combustion engine that drives an electric heat pump (EHP), MCHP/EHP, has been analyzed. It allows a high degree of flexibility in terms of operating conditions, due to the possibility to use the two devices separately supplying electric and thermal (heating and cooling) energy (CCHT, Combined Cooling Heating and Power). The MCHP/EHP is a gas cooling technology that can contribute to optimize the natural gas and electricity consumptions in those countries where the HVAC systems are widespread. In particular, our interest was focused on micro-cogenerators (electric power ≤ 15 kW) at the moment available on the market, based on reciprocating internal combustion engine, that could have a great diffusion in the near future for domestic and light commercial applications. Starting by the results of an intense experimental activity an exergetic, economic and environmental analysis has been carried out to compare the proposed MCHP/EHP system to the conventional one based on separate “production”.
