Porsche Announces New 4-Cylinder Boxer Engine

porscheboxerPorsche’s decision to develop a new four-cylinder engine stems from its need to improve fuel efficiency and emissions ratings across its model line.

The new engine will come standard in the Boxster and Cayman models. There has been talk of a four-cylinder 911, but that’s rather unlikely.

The new engine features a horizontally opposed, “boxer” engine, denoting a flat configuration where the pistons move synchronously in and out, as opposed to in an alternating rhythm. For a displacement, we’ve heard 2.5 liters thrown around as the magic number, but that may be subject to change.

Expect the new engine to come in either direct injected or turbocharged variants. Engine output would probably max at around 395 hp, which is higher than the current output of even the most powerful Boxster and Cayman model variants.

There has also been talk that an entire new family of flat four engines will be developed. The 2.5L variant mentioned above would be the most powerful, but 1.6L and 2.0L variants are also reportedly in the early stages of design. A 1.6L variant would put out 210 hp, the 2.0 would produce 286 hp, while the aforementioned 2.5L would have a base output of 360 hp.

Since the next generation of Cayman and Boxster aren’t due for quite some time, it’ll be at least near the end of the decade by the time this engine sees production, unless the engine appears in the face-lifted versions due to be released in 2016; this is possible but less likely.

Porsche also employs a 2.0L straight four in its upcoming Macan crossover, but that one isn’t anywhere near as powerful or as advanced in terms of efficiency.

The Impact of Fuel Type on Engine Performance

When it comes to choosing the right fuel for your vehicle, several factors should be taken into consideration. These factors include the vehicle’s engine design, manufacturer recommendations, intended usage, and personal preferences.

Component Cleanliness

It can’t be overstated how important the cleaning machines are in the modern engine shop. Shop owners who prioritize effective and efficient cleaning techniques will find success in a more streamlined process.

Billet Blocks and Heads vs. Cast Iron

Billet aluminum has a lower yield strength or higher modulus of elasticity, meaning it will flex, or absorb energy easier under tension or stress than cast aluminum, without incurring permanent damage.

Many times, the flange diameter of the rod nuts will contact the radius around the nut seat on some rods. Some jobs may not warrant the expense of spot facing the nut seat on the connecting rods. In that case, it can be quicker and more effective to just machine a chamfer on the ARP rod nuts.

The CNC Landscape Continues to Grow Inside Engine Shops

Several manufacturers named automation as one of the biggest continuing trends surrounding CNC equipment these days, and it’s clearly a key contributor to a CNC machine’s ability to do more without human interference.

Crankshaft Counterweights

Most engines are internally balanced, meaning all weight adjustment is done on the crankshaft counterweights. However, some stock and modified engines require external balancing due to an increased stroke or larger pistons, and the crankshaft counterweights that would be required to offset the increased inertia simply don’t fit inside the crankcase.
