The B20B engine is a 2.0-liter inline-four engine available for the 2010 Honda Accord with automatic transmission. It produces 173 hp at 6200 rpm and 172 lb-ft of torque at 4000 rpm.
Displacement: 2.0 L; 122 CID
The B20B engine is a 2.0 L inline-four engine that was used in the 1993-1997 Toyota Corolla, 1992-1997 Toyota Celica, 1994-1997 Toyota Carina, and 1994-1997 Toyota Corona.
This engine was later replaced by the 1ZZ-FE in most vehicles (except for the Corona and Celica). The B20B has been phased out and replaced by newer engines such as Honda's K20A2/K24A1.
Bore: 86.0 mm (3.39 in)
The bore of an engine is the diameter of the cylinder. It's one of the most important engine specifications, and it determines displacement (the volume of air and fuel carried in each stroke). The larger the bore, the more air and fuel can be delivered to your car's cylinders.
Stroke: 86.0 mm (3.39 in)
Stroke: 86.0 mm (3.39 in)
Stroke is the distance the piston moves up and down in the cylinder, measured from the top of the piston to the top of the cylinder head. It's determined by bore size; for example, if your engine has a bore size of 3.39 inches (86 millimeters), its stroke will be 3.39 inches long as well.
Compression ratio: 9.1:1
The compression ratio, also known as the CR, is the ratio of the volume of the combustion chamber to the volume of the cylinder. A smaller number indicates a higher compression ratio and will yield better engine efficiency. The maximum amount of air-fuel mixture that can be squeezed into each cylinder is limited by other factors, including heat transfer efficiency and fuel detonation. If a higher CR is used without increasing other parameters (such as camshaft lift), there's a greater risk of knocking or pinging on startup when cold due to compression heating and insufficient lubrication.
A typical street turbocharged engine might have a 12:1 CR while one made for racing applications may have an 18:1 or higher figure depending on its intended use (the faster it has to spin up rpm power output). This means that nearly seven times more air needs to be displaced by each revolution than in an NA application where only 1 barrel worth goes past before being replaced by another at every stroke cycle."
Block material: Cast iron
Another benefit of cast iron is its strength. Cast iron can withstand high temperatures without breaking, which makes it a good material for an engine block. It also makes your engines cheaper to manufacture by allowing you to use less expensive manufacturing processes than you would with aluminum or steel (for example, CNC machining).
However, cast iron has one major drawback when compared to other materials: its brittleness. While this makes it strong in certain directions and resistant to cracking under stress, it also means that cast iron cannot be used for the cylinder head—the most vital part of an engine since it houses the valves and spark plugs that control how much fuel gets mixed with air before entering the cylinders.
Head material: Cast aluminum alloy
- Cast aluminum is lighter than cast iron, which means that a B20B cylinder head will weigh less than a B20A cylinder head.
- Cast aluminum heads dissipate heat better than cast iron heads, so they can run at higher temperatures without damage to the engine. This allows them to make more power because they can run with larger turbochargers and superchargers.
- Cast aluminum is more expensive than cast iron, so it makes sense that you would want one if you're an enthusiast looking for the best of everything or even just someone who wants the most powerful engine possible in their car. You'll also see this material used on race cars because it's lighter and more durable than cast iron, but it doesn't cost as much as titanium parts do either—and don't forget about those performance benefits!
Valvetrain configuration: SOHC, 12 valves, hydraulic lifters with roller followers
- SOHC means Single Overhead Cam.
- 12 valves, with four per cylinder.
- Hydraulic lifters with roller followers. A roller follower is a kind of valvetrain component that moves between the camshaft and rocker arms, converting rotary motion into linear motion. This allows them to open and close valves at different points in the engine's cycle, which increases efficiency by reducing friction and improving overall performance.

Deck height is the distance from the crankshaft centerline to the piston crown. It's an important factor in engine performance, as it affects piston ring sealing and oil consumption, as well as determining what compression ratios can be achieved.
Takeaway:
To wrap up, we've listed the following takeaway points:
- The B20B engine is a 2-liter inline-4 that was designed for use in the Honda Accord and CRV vehicles. It's been used in other models as well, including the Acura Integra and Saturn Vue. Although production of this engine ended in 2001 with the closure of its factory, it's still an incredibly powerful option for drivers looking to upgrade their vehicle's performance.
- Drivers can find a wide selection of parts online at Auto Parts Warehouse or through their local dealer.
