BMW 328i sedans have a 240-horespower, turbocharged, 2.0-liter four-cylinder engine and either the six-speed manual or eight-speed automatic. A 300-horsepower, 3.0-liter, turbocharged six-cylinder comes with the 335i sedan, and it has the same transmission options.
Acceleration and Power. The base 2016 BMW 320i has a turbocharged 2.0-liter four-cylinder engine that produces 180 horsepower, while the 328i comes with a 240-horsepower, turbocharged 2.0-liter four-cylinder engine.
BMW by numbers. The 335i, 328i, 330i, and 325i all have 3.0-liter inline-sixes. The 335i, then, is a twin-turbocharged direct-injection 3.0 that makes 75 percent of the expected power of next year's M3 V-8.

BMW N55 is a turbocharged
straight-six petrol engine that began production in 2009.

BMW 3 Series (E90) The fifth generation of the BMW 3 Series consists of the BMW E90 (sedan), BMW E91 (wagon, marketed as 'Touring'), BMW E92 (coupe) and BMW E93 (convertible) compact executive cars.
Direct injection BMW engines include some 335i coupes and Z4 528i models, and they have been rated some of the best-performing vehicles in the world for the benefits of their direct injection components.
Direct injection technology provides slightly more power and better fuel economy; depending on the application, it's usually in the 10–15 per cent range of improvement. But engine torque delivery can be bumped by as much as 50 per cent.
The result can be engine hesitation and a loss of power—and the need for expensive repairs. It involves modifying the engine to spray a small amount of fuel directly onto the valves to help keep them clean. It's important to note that not all cars with direct injection experience long-term problems.
To keep your car's engine running smoothly, GDI systems should receive a Major Fuel Service every 50,000 km. During this service, your mechanic may remove the intake manifold and clean your valves using a pressurized cleaner. At Searles, we use a triple cleaning process to clear away build up.
The ticking noise is probably the main control solenoid on the high-pressure fuel pump. The reason for the noise level is the extremely high pressures at which the direct-injection fuel system runs. While a port-injection system runs at about 40 psi, GM's direct-injection system can run as high as 1740 psi.
Gasoline direct injection (GDI) is a more advanced version of multiport systems, where fuel is injected directly into the combustion chamber instead of the intake port. Both systems use electronic fuel injectors to spray fuel into the engine, but the difference is where they spray the fuel.
Ford, and other OEMs, have combined PFI with GDI for “advanced dual port and direct-injection,” also known as dual fuel delivery. Examples include: Redesigned Ford 3.5L EcoBoost and V6 engines. Lexus 2GR-FSE engines.
BMW's N54 engine, introduced in the 2007 335i, was the first engine to feature direct injection and turbocharging. Looking at the current BMW line-up, all gasoline engines available in the US are now turbocharged and direct injected.
EFi stands for Electronic Fuel injection (EFi) whereas MPFi or MPi stands for Multi-Point Fuel injection and GDi stands for Gasoline Direct Injection. Thus, there is a fundamental difference between the earlier generation carburetor & newer generation Fuel Injection (EFi) system.
How to Identify a BMW Engine
- Find the identification code for the engine and power plant of your BMW. Each engine has a special place for this code as determined by the factory.
- Write down the code. The code consists of a series of letters and numbers which tell various aspects of your engine.
- Look at the power plant identification code.
