How to distinguish the intake and exhaust camshaft bearing caps of Geely Emgrand?
2 Answers
Methods to distinguish the intake and exhaust camshaft bearing caps of Geely Emgrand: The camshaft has letters marked on it, where IN represents intake and EX represents exhaust. The function of the automobile camshaft is to control the opening and closing of valves. Here is more information about Geely Emgrand: 1. The curb weight of Geely Emgrand is about 1.4 tons. The new Emgrand is equipped with a 1.3-liter turbocharged engine. The 1.3T engine features high torque at low speeds and strong acceleration performance, paired with a mature and stable CVT transmission. 2. Emgrand is a compact sedan under Geely. This model is equipped with a 1.5-liter four-cylinder naturally aspirated engine across the entire lineup, delivering 109 horsepower and a maximum torque of 140 Nm. The engine reaches its maximum power at 6000 rpm and its maximum torque at 4400 rpm.
I've worked on the Geely Emgrand engine multiple times, and the key to distinguishing between intake and exhaust camshaft bearing caps lies in their positions and markings. The intake bearing caps are typically located towards the front of the engine or on the intake manifold side, often engraved with 'IN' or intake symbols, and feel relatively smooth to the touch. The exhaust bearing caps are positioned at the rear or near the exhaust manifold, marked with 'EX' or exhaust symbols, and may be designed slightly thicker to withstand high temperatures. During disassembly, it's crucial to take photos with your phone or mark the original positions with a marker pen to avoid confusion. Installing them incorrectly can cause the camshaft to jam, leading to engine knocking or excessive noise. I recommend referring to the Geely official manual diagrams for guidance. During maintenance, take the opportunity to check lubrication. If there are no markings, measure the dimensions—the intake bore is usually larger to ensure proper airflow. Remembering these small details can save you a lot of trouble and repair costs.
