Product Name: Gasoline Engine Fuel Injection System 

                            Simulator_ Auto Fault

Model Name: YESA-4763

Feature

■ The educational equipment educates overall ignition systems such as 

composition and operation principles of various types of ignition systems 

and injection system.

■ Able to check the overall system at a glance because the compositions of 

ignition system are installed on the panel and the power and wiring terminal 

attached

■ Connection sockets are installed for each sensors, circuits and components 

so that it is able to help wiring practices and measure wave patterns

■ By manipulating the controller, able to adjust intermittent resistance of 

each sensor.

■ Students can understand current of the entire circuit, find out causes and 

changes and take actions.

■ The panel composing the ignition circuit is made with aluminum CNC-treated

panel




Specification

crank gear, cam gear, tester for fuel injection, Ignition circuit : Coil, 

ignition plug, air intake

■ Sensor : Temperature sensor, oxygen sensor, air flow sensor, air temperature

sensor, an engine temperature sensor, exhaust gas sensor, crank sensor and a

cam sensor Power supply

■ Size : Approx. 1,300 X 600 X 1,600mm

■ Weight : Approx. 100kg, key box

Training Contents

■ Measure the wave patterns and check the changes according to RPM speed

■ Engine operation : check the operation of the injector and sparks in the order of

switch plugs(1, 3, 4, 2) and inspect whether normal operation of each sensor

■ Failure code : the device allows to inspect failures on purpose

■ Sensor inspection : can check failure by using variable simulation

Product Name: Gasoline Ignition System Simulator
                            _ Auto Fault 

Model Name: YESA-4252

Feature

■ An effective educational unit that allow students to understand

structure of ignition system devices and operation principles.

■ By installment of connection terminals at sensors, circuits and parts,

students are able to practice wiring and measure waveform.

■ By manipulating the controller, able to check the waveforms and

changes in accordance with RPM speed.

■ Students are able to understand flow of entire circuit, find out what

causes fault and how to repair.

■ The panel composing the ignition circuit is made with aluminum

CNC-treated panel.
