Polestar vehicles, known for their electric performance, are primarily manufactured in China. The brand, a subsidiary of Volvo Car Group and by extension of Zhejiang Geely Holding Group, has positioned its main production facility in Chengdu, China. This strategic location benefits from China's strong push towards electric vehicles (EVs) and its well-established automotive manufacturing infrastructure. Additionally, the Luqiao plant, also in China, handles production for some models like the Polestar 2. Despite its Chinese manufacturing roots, Polestar retains a Swedish heritage in design and engineering, reflecting its Volvo lineage. This global blend is part of Polestar's identity, aiming to combine Swedish innovation with Chinese efficiency in EV manufacturing.

A 2-cycle diesel engine operates on the principle of completing a power cycle in just two strokes of the piston: combustion and compression. Unlike its 4-stroke counterpart, it lacks dedicated intake and exhaust strokes. Here's how it works:
1. **Compression Stroke**: As the piston moves up, it compresses the air in the cylinder, dramatically increasing its temperature.
2. **Power Stroke**: Just before the piston reaches the top, fuel is injected into the highly compressed air, causing spontaneous combustion due to the high temperature. The expanding gases from the combustion push the piston down. Near the bottom of the stroke, exhaust ports (and intake ports in some designs) are uncovered by the piston, allowing exhaust gases to escape and fresh air to enter, helped by a blower or turbocharger in most engines.
This design allows for continuous operation with power being generated every other stroke, making it very efficient in terms of size and weight to power output ratio. However, due to challenges like emissions control and efficiency at low speeds, 2-cycle diesel engines are predominantly found in applications requiring a high power-to-weight ratio, such as in large maritime engines, some generators, and specialized industrial applications. Their relatively simpler construction compared to 4-stroke engines can also result in reduced maintenance requirements but at the cost of increased fuel consumption and, typically, higher emissions.
The 322 Pace Bus is a public transportation route operated by the Pace Suburban Bus system in the Chicago, Illinois area. It runs between the CTA Green Line Austin Station in Chicago and the Westfield Shoppingtown in suburban Westfield. The routing includes major destinations such as the Oak Park Hospital, River Forest Town Center, and the Elmwood Park Village Hall. The service runs primarily on weekdays and Saturdays, with reduced service on Sundays. All Pace buses are accessible and equipped with bike racks.
