MOTOR RATHA DANUMA – 1

For correct operation of the complex system in motor vehicles not only the technicians, drivers and vehicle owners too have to be knowledgeable of these functions. Many of them other than technicians show  very little interest to acquire knowledge on new motor vehicle technology. It is difficult for these persons to gain knowledge from the texts available for technical students and technicians as these are too complicated. This book on new technology is written in a very simple manner to make it easy for them to understand the technical knowledge they require.

MOTOR RATHA DANUMA – 2

Our technicians and vehicle owners switch to LP gas conversions and everybody accepts the fact that they are financially benefited by this. The poisonous gas emitted to the atmosphere, compared to petrol, from gas converted vehicle is less to a certain extent. To vehicle achieve maximum benefits, the gas conversion must be done at a lower cost and safety factor taken into consideration. Attempt has been made in this text to impart this knowledge, very simplified, how the gas conversions could be done very successfully, even the vehicle owners could understand.

MOTOR RATHA PETROL ENGINE

Today motor vehicles totally use 4 stroke engines. Petrol engines and diesel engines have identical mechanical functions. These engines differ only on the fuels used and ignition systems in them. Therefore though this text is written on the basic petrol engine mechanical system it is applicable for the mechanical system of a diesel engine too.

MOTOR RATHA CARBURETOR

Today though fuel injection systems are only used I all modern motor vehicles, the technicians will need the knowledge of the carburetors for some more years to come. The reason for this is that the carburetor vehicles which are in use today will go on for some more years. This text is specially prepared to explain the functions of the carburetor and the elementary principles of it rather than carburetor servicing.

MOTOR VEHICLE IGNITION SYSTEM

To find faults in a complex ignition system and pin pointing the faulty part, changing and repairing the fault could only be achieved by the technician if he is conversant of the design and the function of the ignition system. The only way this is possible is to study the evolution of the ignition system step by step to the modern system. This text shows the evolution of the ignition systems up to transistorized coil ignition system in a simple and very correct way.

ELECTRONICALLY CONTROLLED IGNITION SYSTEMS

The modern day petrol motor vehicles are controlled by computer controlled ignition systems. To find a fault in this system the complete functioning of the system must be understood. Even without this knowledge certain repairs could be done by technicians. This is what most people do by changing each and every part in the system till the fault is rectified. This type of repair could take a long time and could cause a big loss for the vehicle owner.
This text has paved way for this not to happened and has provided information regarding all the functions of this system very well explained..

MOTOR VEHICLE ELECTRIC ELECTRONIC STUDIES

The modern motor vehicles are manufactured in a very complex manner and has several circuits and each of which are controlled by several computer controlled electronic units. Presently many of this type of vehicles are used in Sri Lanka, and the future imports will also be vehicles of this nature. To repair these vehicles the technicians should be able to correctly identify the faults. For this purpose this text explains the functions of the circuits giving the necessary electric electronics knowledge.

MOTOR VEHICLE AIR CONDITIONING

Motor vehicle air-conditioners are day by day getting more and more complex and today they are controlled by digital climatic control systems. Yet these air condition systems are repaired by untrained technicians who only have practical experience. With their experience these technicians somehow manage to repair these systems to cool. The modifications they do when repairing these systems. Effects inactivity of certain functions and damage to certain functions. which the technicians or the vehicle owner will not be aware. Because of this short coming this text has, from the very beginning, set up to educate the technicians who have only practical knowledge and experience to be able to understand the very complicated digital climatic control system prevailing today, in a very simple manner.

ELECTRONIC DIESEL INJECTION

If electronic technology was introduced to a vehicle which had the earlier system. Definitely there will be a fault in the old system which cannot be corrected. In a diesel engine by completely removing the mechanical speed control governor system and introducing a electronically controlled governor system proves that the earlier produced diesel engines had faults in them. By studing the earlier engine faults and also the solutions introduced by the manufacturers to cover up the faults and the hidden technology in electronic diesel injection could be learned from this book.

FUEL INJECTION AND MOTRONICS SYSTEMS

Petrol injection technology which was introduced to motor vehicles, from air craft technology continue the use of petrol injection in place of carburetors. The petrol injection system which evolved in this manner has never been published by any other language in detail other than this large text in sinhala for the first time in Sri Lanka.

ABS BREAKING SYSTEMS AND TRACTION CONTROL

Modern day motor vehicles have various traction control systems and are known in different names, and used in various ways. This system which was limited to very luxury and highly sophisticated vehicles, is now seen introduced in middle class motor vehicles as well. As all traction control systems are designed in relation to ABS (Anti-Locking Breaking System), the first aprt in this text is set aside to introduce the existing ABS systems. Also the traction control systems like the drive by wire electronic systems are separately introduced in this text.
