Cleaning<\/h5>\n<p>The tank heats the cleaning fluid to remove carbon deposits faster and improve the cleaning effect on injectors.<\/p>\n<\/li>\n<li>\n<h5>Nine Test Functions<\/h5>\n<p>Idling, medium speed, high speed, accelerating and shifting speed tests, a leak checking test, and idling, medium-speed and high-speed spray value tests.<\/p>\n<\/li>\n<li>\n<h5>Real-Time Monitoring<\/h5>\n<p>An LED display, pressure gauge, graduated glass tubes, liquid level gauge and control panel show what is happening during each test.<\/p>\n<\/li>\n<li>\n<h5>Easy Fluid Recovery<\/h5>\n<p>Drain valves let you recover used cleaning fluid and testing fluid after use.<\/p>\n<\/li>\n<li>\n<h5>Short-Circuit Protection<\/h5>\n<p>If the machine short-circuits, the internal fuse trips and shuts it down to prevent electric shock.<\/p>\n<\/li>\n<li>\n<h5>Aluminum Alloy Build<\/h5>\n<p>Lightweight and strong, with good airtightness and corrosion resistance.<\/p>\n<\/li>\n<\/ol>\n<\/section>\n<section
