주요사양
Fuel efficiency meter
Fuel Consumption Meter
- Coriolis force type flowmeter
- The Coriolis force measurement method enables real-time measurement of fuel quantity that changes according to engine conditions
- This measurement method enables real-time measurement of fuel flow rate, temperature, and density of consumed fuel
- Fuel conditioning device (optional)
- Built-in bubble detector enables precise fuel flow measurement even in the presence of air bubbles
- Precise temperature control is possible through heating/cooling control
Air flow meter
Intake Air Flowmeter
- Engine Tech's air flowmeter uses Meriam's LFE (Laminar Flow Element), renowned for high precision and supplied to the U.S. EPA, ensuring high measurement reliability
- A wide range of options available to match engine capacity
- Equipped with a computer (optional) for real-time measurement data output and calibration
Engine Coolant Temperature Controller
Engine Water Temp Controller
- Precise engine coolant temperature control (engine inlet/outlet control)
- Heating and Cooling Output Control
- Alarm Indicator Light Installation
- Application of various safety devices
Engine Thermal Shock Tester
Thermal Shock Controller
- 0~110°C temperature control
- Compact size
- Fluid engineering tank design
- Pneumatic actuator heating/cooling switching
- Automation integrated management (communication control)
- Current status and control status display
- Manual/Auto control
- Application of various safety devices
Engine Oil Temperature Controller
Engine Oil Temp Controller
- Precise engine oil temperature control (engine inlet/outlet control)
- Heating and Cooling Output Control
- Alarm Indicator Light Installation
- Application of various safety devices
Exhaust Back Pressure Control System
Engine Exhaust Back Pressure Controller
- Exhaust back pressure refers to the stagnant pressure in the exhaust system caused by resistance from the exhaust pipe, muffler, and catalytic converter
- Exhaust back pressure increases as engine speed and load increase, causing a decrease in power output and fuel efficiency
- The EGR system reduces the concentration of nitrogen oxides in exhaust gas and has the effect of lowering combustion temperature
- The valve is located in the intake manifold and controls the opening of a small passage between the exhaust pipe and intake pipe
- Certain types of EGR valves are opened by negative pressure, and a certain amount of exhaust back pressure is required to open the valve with this negative pressure
- The exhaust back pressure control system enables monitoring and control of exhaust back pressure during engine testing
- Exhaust back pressure can be a variable in engine performance and should be considered in engine development
