The oil cooler heat exchanger is mounted to the lower right side of the engine and is used to heat or cool engine oil. This bypass valve is used to continue providing oil to the engine in the event the oil filter becomes plugged. The lubrication system also includes an oil filter bypass valve located inside the filter thread nipple. The oil control valve is controlled by the engine control module. The continuously variable oil pump has an oil control valve that controls the oil flow to the oil pump, thereby controlling the oil pressure in the main gallery. The lubrication system includes a continuously variable oil pump, an oil filter bypass valve, and an oil heat exchanger. Once properly cleaned, the oil pan is reusable. These oil pans are equipped with M5 jackscrews for easy removal. The oil pan must not be used for lifting the engine as noted by the icon on the pan. The lower oil pan is made of plastic and is attached at the engine block lower structural extension. The powdered metal connecting rods are fractured at the connecting rod journal and machined for proper clearance. The chromium steel pins are designed to be full-floating and must be serviced with the pistons as an assembly. The pistons use two compression rings and one oil control ring assembly. Its cast iron top ring provides added strength. The cast aluminum pistons in the 1.3L (元T) engine are a lightweight and low friction design with a recessed top and a barrel shaped, graphite-coated skirt. A harmonic balancer controls torsional vibration. Six counterweights have been scalloped for mass reduction and precision engine balance. The crankshaft is made of forged micro alloy steel. This design promotes the maximum effectiveness of the balance shaft system and further reduces engine noise and vibration. The engine oil pump supplies pressure to the hydraulic tensioner, which provides the chain's tension. The balance shaft and oil pump are driven by the balance shaft chain. The oil pump is attached to the lower structural extension of the engine block. The single balance shaft is internal to the engine block. The fuel injectors are located under the intake ports. The exhaust manifold is integrated into the cylinder head. Each combustion chamber contains four valves and is designed for increased swirl efficiency of the incoming air charge to maximize gasoline combustion efficiency. The cylinder head is a dual overhead camshaft design made of cast aluminum alloy. The lower structural extension forms the lower portion of the crankcase to promote cylinder block rigidity and reduce engine noise and vibration. There are four crankshaft bearings with the thrust bearing being located on the third bearing from the front of the engine. The aluminum alloy engine block is made by high pressure die casting with three cast-in-place iron cylinder liners called cylinder set strategy (CSS). Displacement: 1.2L, 1199 cc, 73.2 CID (cubic inch displacement).Fuel System: Spark ignited direct injection (SIDI).Valve Configuration: Dual overhead camshaft (DOHC) with variable valve timing (VVT).Displacement: 1.35 L, 1341 cc, 81.8 CID (cubic inch displacement).GM’s new three-cylinder engines are built at its Ramos Arizpe plant in Mexico and are then shipped to GM Korea’s Bupyeong facility in Incheon, South Korea, which is building both the 2020-2021 Buick Encore GX and the related 2021 Chevrolet Trailblazer. The new 1.2T and 1.3T engines were designed through a partnership with GM's former Opel subsidiary (now owned by PSA), and the Shanghai Automotive Industry Corporation (SAIC), and MG Motor. It is the built off the new cylinder set strategy (CSS) engine architecture, optimizing efficiency and performance. The 1.3T is an advanced, power dense, inline three-cylinder engine, producing 115 hp (86 kW) per liter.
