Fuel at a glance
Key metrics to place the journal before deciding whether it fits your manuscript and career goals.
What makes this journal worth targeting
- IF 7.5 puts Fuel in a visible tier — citations from papers here carry real weight.
- Scope specificity matters more than impact factor for most manuscript decisions.
- Acceptance rate of ~~40-50% means fit determines most outcomes.
When to look elsewhere
- When your paper sits at the edge of the journal's stated scope — borderline fit rarely improves after submission.
- If timeline matters: Fuel takes ~~100-130 days median. A faster-turnaround journal may suit a grant or job deadline better.
- If open access is required by your funder, verify the journal's OA agreements before submitting.
How to use this page well
These pages work best when they behave like tools, not essays. Use the quick structure first, then apply it to the exact journal and manuscript situation.
Question | What to do |
|---|---|
Use this page for | Getting the structure, tone, and decision logic right before you send anything out. |
Most important move | Make the reviewer-facing or editor-facing ask obvious early rather than burying it in prose. |
Common mistake | Turning a practical page into a long explanation instead of a working template or checklist. |
Next step | Use the page as a tool, then adjust it to the exact manuscript and journal situation. |
Quick answer: a strong Fuel cover letter proves your work has practical relevance to real fuel systems. With an IF of ~7-8 and a 25-30% acceptance rate, the editor screens for experimental grounding and a clear connection to fuel science rather than pure computational elegance.
What Fuel Editors Screen For
Criterion | What They Want | Common Mistake |
|---|---|---|
Fuel-science relevance | Paper belongs in a fuel journal, not a materials or pure chemistry journal | Mentioning fuel in the conclusions of a materials-science paper |
Experimental grounding | Real experimental data or real-world validation | Pure computational study with no experimental validation |
Practical novelty | Something new beyond a different feedstock or blend ratio | Running the same experiment with a different fuel and calling it novel |
Engineering consequence | Finding matters outside the lab in terms an engineer would care about | Lab-scale results disconnected from real fuel system applications |
Journal distinction | Clear reason for Fuel vs. Combustion and Flame or a general energy journal | Submitting combustion fundamentals without direct fuel application |
What the official sources do and do not tell you
Elsevier's Guide for Authors lists scope areas: combustion, alternative fuels, emissions, fuel processing, and carbon capture. It asks for a cover letter, suggested reviewers, graphical abstract, and highlights. What it does not say is how aggressively the editors enforce the experimental-validation requirement.
Fuel is not a general energy journal and not a pure chemistry journal. The editorial team includes academic editors who are active researchers, not full-time publishing staff. They spot vague claims fast because they know the literature, but they also process submissions alongside their own research, so they will not spend long on a letter that buries the finding.
The ~30-40% desk-rejection rate is the number that matters. Nearly one in three papers never reaches a reviewer, and the decision usually happens within a week based on the abstract and cover letter alone.
What the editor is really screening for
At triage, the editor is usually asking:
- Does this paper belong in Fuel, or is it really a materials-science or pure-chemistry paper that mentions fuel in the conclusions?
- Is there experimental or real-world grounding, or is this a computational study with no validation?
- What is actually new beyond running the same experiment with a different feedstock or blend ratio?
- Does the finding matter outside the lab, stated in terms an engineer would care about?
A cover letter that answers the first question in the opening paragraph will survive triage.
A practical template you can adapt
Dear Editor,
We submit the manuscript "[TITLE]" for consideration as a
research article in Fuel.
[STATE THE FUEL PROBLEM AND MAIN FINDING IN 2-3 SENTENCES.
Example: "Ammonia-hydrogen blends are a candidate for
zero-carbon marine engines, but ignition delay data above
30 bar are scarce. We report shock-tube measurements at
30-80 bar and 1000-1600 K, filling a gap that limits kinetic
model validation for high-pressure marine conditions."]
[CONNECT TO PRACTICE IN 2-3 SENTENCES. Example: "Existing
mechanisms overpredict ignition delay by 40-60% above 50 bar.
Our updated mechanism reduces prediction error to under 10%
across the full pressure range."]
[STATE NOVELTY IN 1-2 SENTENCES. Example: "Previous data were
limited to below 20 bar. This work extends the database to
conditions relevant to modern two-stroke marine diesel engines."]
The work is original, not under consideration elsewhere, and
approved by all authors.
Sincerely,
[Name]The opening sentence naming the fuel system and the finding is the element that matters most.
Mistakes that make these letters weak
- Starting with a literature-review preamble instead of your result, which signals you have no specific story to tell
- Submitting a modeling paper with no mention of which experimental dataset you validated against
- Reporting incremental blend studies (different ratio, same engine) without explaining what was unexpected
- Claiming novelty through obscurity ("first study on [rare feedstock] in [specific engine]") rather than through new understanding
- Omitting the practical connection: if you cannot say what your finding means for engine design, emissions, or fuel processing, the editor will assume it means nothing
What should drive the submission decision instead
Before polishing the cover letter, check whether the paper's center of gravity is actually fuel science. If the word "fuel" does not appear until the conclusions, the manuscript probably belongs in Applied Catalysis B or Energy & Fuels instead. Review the Fuel Guide for Authors and ask whether the practical fuel-system connection runs through the entire paper, not just the framing.
Practical verdict
Fuel editors eliminate submissions that read like pure modeling exercises or papers where the fuel connection is cosmetic. The cover letter's job is to prove yours is neither.
So the useful takeaway is this: name the fuel system, state the finding with numbers, and connect it to practice in the first paragraph. A Fuel cover letter framing and fuel-system scope check is the fastest way to pressure-test that framing before submission.
In Our Pre-Submission Review Work with Manuscripts Targeting Fuel
In our pre-submission review work with manuscripts targeting Fuel, the most common cover-letter failure is not weak prose. It is weak journal identity. Editors are usually deciding whether the manuscript is genuinely about fuel systems or whether it is a combustion, catalysis, or modeling paper wearing fuel language on top.
The first failure is cosmetic fuel framing. A manuscript about catalysts, materials, or simulations can still be excellent work and still not read like a Fuel paper if the cover letter does not say what actual fuel-system problem is being solved. Editors want the letter to surface the fuel itself, the operating context, and the engineering consequence immediately.
The second failure is incremental novelty dressed up as practical relevance. We see many letters that say a manuscript is the first to test a specific feedstock, blend ratio, or waste-derived precursor. That is rarely persuasive by itself. The stronger argument is what changed for ignition, emissions, upgrading, storage, stability, or processing performance and why that matters to people working on real fuel systems.
The third failure is burying the validation story. If the manuscript includes experiments, pilot-scale runs, or an explicit benchmark against realistic operating data, the letter should say so fast. When the validation detail is hidden until later, the paper often reads like a pure modeling submission and gets triaged as one.
A Fuel journal desk-rejection risk and citation completeness check is the fastest way to test whether the letter is making the fuel-system case clearly enough before submission.
Submit If / Think Twice If
Submit if:
- the paper's center of gravity is genuinely fuels, fuel processing, emissions, combustion in a fuel context, or another clear fuel-system problem
- the first paragraph can name the fuel system and the main result with numbers
- you can point to experimental grounding, pilot data, or a real operating benchmark instead of modeling alone
- the practical consequence is specific, such as ignition behavior, emissions control, upgrading yield, storage stability, or system efficiency
Think twice if:
- the paper is really catalysis, materials, or combustion fundamentals with only cosmetic fuel framing
- the main novelty is a new feedstock or blend ratio without a stronger engineering conclusion
- the validation story is too thin to overcome the impression of a pure modeling paper
- the real fit case is stronger for Combustion and Flame, Applied Catalysis B, Energy, or another adjacent journal

Elsevier cover letter requirements
Keep under one page. Explain scope fit and emphasize novelty. Do not include funding information, author declarations, or reviewer suggestions, handled separately in submission system.
A Fuel journal desk-rejection risk and citation completeness check scores desk-reject risk.
Before you submit
A Fuel journal submission readiness check takes about 1-2 minutes and identifies the specific issues that trigger desk rejection at your target journal.
Frequently asked questions
Fuel accepts roughly 25-30% of submissions. Desk rejection runs 30-40%, often within one to two weeks, driven mainly by scope mismatch or pure modeling without experimental validation.
Not strictly, but submitting without one is risky. The cover letter is your main tool for showing the editor that your work has practical fuel-science relevance. Papers without one are more likely to be desk-rejected.
Emphasize the practical relevance of your findings to real fuel systems. State the fuel problem, what you found, and how results affect fuel design, engine operation, or emissions. Pure modeling without experimental validation is a common desk-rejection trigger.
Combustion and Flame prioritizes fundamental combustion science and flame dynamics. Fuel has broader scope covering fuel chemistry, processing, alternative fuels, and emissions. If your paper is about flame structure with no direct fuel application, Combustion and Flame fits better.
