OUJIAXIN ENGINE Volkswagen EA111 1.4T concave

Description

The EA111 series of internal combustion engines was initially developed by Audi under Ludwig Kraus’s leadership and introduced in 1974 in the Audi 50 and shortly after, in the original Volkswagen Polo. It is a series of water-cooled inline three- and inline four-cylinder petrol and diesel engines, in a variety of displacement sizes. This overhead camshaft engine features a crossflow cylinder head design. The camshaft is driven by a toothed belt from the crankshaft, this belt also provides the drive for coolant pump. The oil pump is directly driven by crankshaft, petrol pump and distributor are driven by camshaft. Other “V” belt-driven accessories are the alternator and (if fitted) power steering, and air-conditioning pump. In transverse mount configuration, the exhaust side is towards the vehicle firewall, in longitudinal configuration, the exhaust side is to the right as you face front in either left or right-hand drive vehicles.

Main cooling circulation system. The main cooling circuit can be divided into two circuits, one circuit flowing through the cylinder block and the other circuit flowing through the cylinder head. Through the dual thermostats, the split flow of coolant is realized. A third flows through the engine block, where it cools the cylinders. Two-thirds of it flows through the cylinder head to cool the combustion chamber. Thermostat 1 controls the coolant for the cylinder block, and thermostat 2 controls the coolant for the cylinder head.
