Problem: Text: Diesel fuel pumps operate at a much higher pressure due to the engine's specs and are usually mechanical pumps such as common rail radial piston pump, common rail two piston radial, inline pump, port and helix, and metering unit design. Radial piston pumps used in cars and trucks are fuel lubricated, this helps with keeping oil out of the high pressure fuel. Oil in the fuel can raise emissions and clog injectors. Many diesel engines are common rail, which means all the injectors are supplied by one pipe full of high pressure fuel supplied by the fuel pump. Common rails dampen the pressure fluctuations when fuel is used by each injector and pumped into the cylinder. Common rails also make it easier for the fuel pressure to be measured by one device instead of one per cylinder. Port and Helix (plunger type) high pressure fuel pumps are most commonly used in marine diesels because of their simplicity, reliability, and its ability to be scaled up in proportion to the engine size.

Question: does a diesel engine have a fuel pump?
A: yes

Problem: Text: In July, Fleischer described the film as having ''no heroes'', and said that they were planning a ''huge world'' with many characters while developing the film; he revealed that another symbiote, Riot, would be appearing as a villain in the film. Additionally, he confirmed that Spider-Man would not be appearing in the film but that a crossover with that character could happen in a future film. Since Venom's origin is not tied to Spider-Man in the film, as it is in the comics, it did not make sense for the filmmakers to add a version of Spider-Man's symbol to Venom's chest. However, they still wanted to be as accurate to the comic designs as possible and Fleischer noted an additional issue of an all-black character being difficult to see in night scenes, so Venom has a unique symbol on his chest instead in the film which is formed from the white veins of the symbiote. It was important for Fleischer to honor the violence of the character from the comics, where ''he bites people's heads off and eats brains. It would be weird to make a movie with Venom if he wasn't doing that.''

Question: is spider man in the new venom movie?
A: no

Problem: Text: A referendum on the political status of Puerto Rico was held in Puerto Rico on June 11, 2017. The referendum had three options: becoming a state of the United States, independence/free association, or maintaining the current territorial status. Those who voted overwhelmingly chose statehood by 97%; turnout, however, was 23%, a historically low figure. This figure is attributed to a boycott led by the pro-status quo PPD party.

Question: did puerto rico vote to become a us state?
A:
yes
