2013 BMW 135i － ENGINE N55 - Service Information
ENGINE
N55 - Service Information
INTRODUCTION
The N55 engine is the successor to the N54, Re-engineering and modifications have made it possible to now use only one exhaust turbocharger. Against the backdrop of reduced costs and improved quality, the technical data have remained virtually the same.
Fig. 1: Identifying BMW N55 Engine
ENGINE SYSTEM OVERVIEW
The following provides an overview of the features of the N55 engine:
Crankcase:
Large longitudinal ventilation holes inter-connect the crankcase lower chambers and relieve unwanted crankcase pressure between cylinders.
Modified oil galleries enhance the supply of oil to vacuum pump.
Crankshaft: Is light weight design and has an asymmetric counterweight arrangement.
Pistons and connecting rods:
A specially formed bushing/bore in small end of the connecting rods evenly distributes the force of the pistons on the power stroke.
Lead-free bearing shells are installed on the big-end of the connecting rods.
Cylinder head:
Specially designed water passages intergraded into the cylinder head enhance injector cooling.
The combustion chambers are machined to work in conjunction with the Valvetronic III system with regard to promoting air turbulence and mixture formation.
Crankcase ventilation:
In contrast to the N54, the N55 crankcase ventilation does not use cyclone separators.
The cylinder and head cover have integrated blow-by passages that connect the crankcase ventilation directly to the intake ports.
VANOS:
The N55 VANOS oil passages are simplified compared to the N54 engine.
The solenoid valves have integrated non-return valve and 3 screen filters.
The VANOS units are of a lightweight design for increased adjustment speed and have a reduced susceptibility to soiling.
Valvetrain:
The N55 is the first BMW turbo engine to incorporate Valvetronic.
The valvetrain is a new designed that combines Valvetronic III with Double VANOS.
With Valvetronic III the 3rd generation brushless servomotor is introduced.
The position detection sensor of eccentric shaft is now integrated in the servomotor.
Oil supply:
An enhanced and simplified oil circuit design is used.
The inlet pipe, oil deflector, and oil collector are combined in one component.
Oil pump uses a Duroplast slide valve and it is electronically controlled based on a characteristic map within the engine management.
