Volvo Penta 4 cylinder b30

The Volvo Penta B30 engine series was a 4-cylinder gasoline engine line produced by Volvo Penta, a subsidiary of the Swedish automotive manufacturer Volvo. The B30 engines were widely used in various marine and industrial applications during the 1960s and 1970s. Here's an overview of the history of the Volvo Penta 4-cylinder B30 engines:

Development and Introduction: The development of the B30 engine series began in the late 1950s with the aim of creating a powerful and reliable gasoline engine for marine and industrial use. Volvo Penta introduced the B30 engine series in 1969 as a successor to the earlier B20 engine series.

Technical Specifications: The Volvo Penta B30 engines were inline 4-cylinder engines with a displacement of 3.0 liters (183 cubic inches). The engines featured an overhead valve (OHV) design with a cast-iron block and cylinder head, providing durability and strength. They had a bore and stroke of 92mm x 80mm and a compression ratio of 8.7:1.

Power Output: The power output of the B30 engines varied depending on the specific model and configuration. The original B30 engine produced around 130 horsepower (HP), while later variants, such as the B30A and B30B, had power outputs ranging from 140 HP to 165 HP. The engines were known for their smooth operation and reliable performance.

Applications: The Volvo Penta B30 engines found extensive use in marine applications, powering various types of boats and watercraft. They were often employed as inboard engines, providing propulsion for pleasure boats, yachts, and smaller commercial vessels. The B30 engines were also utilized in industrial applications, such as powering generators, pumps, and other stationary equipment.

Legacy and Replacements: The B30 engines enjoyed a long production run and were well-regarded for their performance and reliability. However, as emission regulations became more stringent in the 1980s, the B30 engines were gradually phased out. Volvo Penta introduced newer engine series, such as the AQ series and later the 4-cylinder GXi/GXE models, to comply with the stricter emission standards and offer improved efficiency.

Today, while the B30 engines are no longer in production, there is still a dedicated community of boat enthusiasts and restorers who appreciate and maintain these vintage engines. Their historical significance and robust design make them sought-after classics for those looking to restore and preserve older boats.

Overall, the Volvo Penta 4-cylinder B30 engines played a significant role in powering boats and industrial equipment during the 1960s and 1970s. They represented Volvo Penta's commitment to providing reliable and efficient power solutions for a wide range of applications.
